Jabir b. Samura reported that the Apostle of Allah (may peace be upon him) observed (Nafl) prayer sitting before his death.

A man fell ill and a cry was raised (for his death). So his neighbour came to the Messenger of Allah (saws) and said to him: He has died. He asked: Who told you? He said: I have seen him. The Messenger of Allah (saws) said: He has not died. He then returned.

A cry was again raised (for his death). He came to the Messenger of Allah (saws) and said: He has died. The Prophet (saws) said: He has not died. He then returned.

A cry was again raised over him. His wife said: Go to the Messenger of Allah (saws) and inform him. The man said: O Allah, curse him.

He said: The man then went and saw that he had killed himself with an arrowhead. So he went to the Prophet (saws) and informed him that he had died.

He asked: Who told you? He replied: I myself saw that he had killed himself with arrowheads. He asked: Have you seen him? He replied: Yes. He then said: Then I shall not pray over him.

'A'isha reported that the Messenger of Allah (may peace be upon him) died (in this very state) that he observed most of his (Nafl) prayers in a sitting position.

as follows in Hadith 297.

Narrated Abu Huraira:

We were in the company of Allah's Apostle in a Ghazwa, and he remarked about a man who claimed to be a Muslim, saying, "This (man) is from the people of the (Hell) Fire." When the battle started, the man fought violently till he got wounded. Somebody said, "O Allah's Apostle! The man whom you described as being from the people of the (Hell) Fire fought violently today and died." The Prophet said, "He will go to the (Hell) Fire." Some people were on the point of doubting (the truth of what the Prophet had said) while they were in this state, suddenly someone said that he was still alive but severely wounded. When night fell, he lost patience and committed suicide. The Prophet was informed of that, and he said, "Allah is Greater! I testify that I am Allah's Slave and His Apostle." Then he ordered Bilal to announce amongst the people: 'None will enter Paradise but a Muslim, and Allah may support this religion (i.e. Islam) even with a disobedient man.'

The Prophet said, "The Prophet Abraham emigrated with Sarah and entered a village where there was a king or a tyrant. (The king) was told that Abraham had entered (the village) accompanied by a woman who was one of the most charming women. So, the king sent for Abraham and asked, 'O Abraham! Who is this lady accompanying you?' Abraham replied, 'She is my sister (i.e. in religion).' Then Abraham returned to her and said, 'Do not contradict my statement, for I have informed them that you are my sister. By Allah, there are no true believers on this land except you and 1.' Then Abraham sent her to the king. When the king got to her, she got up and performed ablution, prayed and said, 'O Allah! If I have believed in You and Your Apostle, and have saved my private parts from everybody except my husband, then please do not let this pagan overpower me.' On that the king fell in a mood of agitation and started moving his legs. Seeing the condition of the king, Sarah said, 'O Allah! If he should die, the people will say that I have killed him.' The king regained his power, and proceeded towards her but she got up again and performed ablution, prayed and said, 'O Allah! If I have believed in You and Your Apostle and have kept my private parts safe from all except my husband, then please do not let this pagan overpower me.' The king again fell in a mood of agitation and started moving his legs. On seeing that state of the king, Sarah said, 'O Allah! If he should die, the people will say that I have killed him.' The king got either two or three attacks, and after recovering from the last attack he said, 'By Allah! You have sent a satan to me. Take her to Abraham and give her Ajar.' So she came back to Abraham and said, 'Allah humiliated the pagan and gave us a slave-girl for service."

The Prophet said, "On every Muslim there is enjoined (a compulsory) Sadaqa (alms)." They (the people) said, "If one has nothing?' He said, "He should work with his hands so that he may benefit himself and give in charity." They said, "If he cannot work or does not work?" He said, "Then he should help the oppressed unhappy person (by word or action or both)." They said, "If he does not do it?" He said, "Then he should enjoin what is good (or said what is reasonable).' They said, "If he does not do that''' He said, "Then he should refrain from doing evil, for that will be considered for Him as a Sadaqa (charity) . "

from his father from his grandfather that the Prophet said, "Every Muslim has to give in charity." The people asked, "O Allah's Prophet! If someone has nothing to give, what will he do?" He said, "He should work with his hands and benefit himself and also give in charity (from what he earns)." The people further asked, "If he cannot find even that?" He replied, "He should help the needy who appeal for help." Then the people asked, "If he cannot do that?" He replied, "Then he should perform good deeds and keep away from evil deeds and this will be regarded as charitable deeds."

had piles, so I asked the Prophet about the prayer. He said, "Pray while standing and if you can't, pray while sitting and if you cannot do even that, then pray Lying on your side."

I asked the Prophet, "What is the best deed?" He replied, "To believe in Allah and to fight for His Cause." I then asked, "What is the best kind of manumission (of slaves)?" He replied, "The manumission of the most expensive slave and the most beloved by his master." I said, "If I cannot afford to do that?" He said, "Help the weak or do good for a person who cannot work for himself." I said, "If I cannot do that?" He said, "Refrain from harming others for this will be regarded as a charitable deed for your own good."

I asked `Abdullah bin `Umar, "O Abu `Abdur-Rahman! I saw you doing four things which I never saw being done by anyone of you companions?" `Abdullah bin `Umar said, "What are those, O Ibn Juraij?" I said, "I never saw you touching any corner of the Ka`ba except these (two) facing south (Yemen) and I saw you wearing shoes made of tanned leather and dyeing your hair with Hinna (a kind of red dye). I also noticed that whenever you were in Mecca, the people assume Ihram on seeing the new moon crescent (1st of Dhul-Hijja) while you did not assume the Ihlal (Ihram) -(Ihram is also called Ihlal which means 'Loud calling' because a Muhrim has to recite Talbiya aloud when assuming the state of Ihram) - till the 8th of Dhul-Hijja (Day of Tarwiya). `Abdullah replied, "Regarding the corners of Ka`ba, I never saw Allah's Apostle touching except those facing south (Yemen) and regarding the tanned leather shoes, no doubt I saw Allah's Apostle wearing non-hairy shoes and he used to perform ablution while wearing the shoes (i.e. wash his feet and then put on the shoes). So I love to wear similar shoes. And about the dyeing of hair with Hinna; no doubt I saw Allah's Apostle dyeing his hair with it and that is why I like to dye (my hair with it). Regarding Ihlal, I did not see Allah's Apostle assuming Ihlal till he set out for Hajj (on the 8th of Dhul-Hijja).

'Ubai bin Juraij said to `Abdullah Ben `Umar, "I see you doing four things which are not done by your friends." Ibn `Umar said, "What are they, O Ibn Juraij?" He said, "I see that you do not touch except the two Yemenite corners of the Ka`ba (while performing the Tawaf): and I see you wearing the Sabtiyya shoes; and I see you dyeing (your hair) with Sufra; and I see that when you are in Mecca, the people assume the state of Ihram on seeing the crescent (on the first day of Dhul-Hijja) while you do not assume the state of Ihram till the Day of Tarwiya (8th Dhul Hijja)." `Abdullah bin `Umar said to him, "As for the corners of the Ka`ba, I have not seen Allah's Apostle touching except the two Yemenite corners, As for the Sabtiyya shoes, I saw Allah's Apostle wearing leather shoes that had no hair, and he used to perform the ablution while wearing them. Therefore, I like to wear such shoes. As regards dyeing with Sufra, I saw Allah's Apostle dyeing his hair with it, so I like to dye (my hair) with it. As regards the crescent (of Dhul-Hijja), I have not seen Allah's Apostle assuming the state of Ihram till his she-camel set out (on the 8th of Dhul-Hijja).
