“The best of witnesses is the one who gives his testimony before he is asked for it.”

that in the time of Allah's Messenger (SAW) a man took a vow to slaughter camels at Bawana. So, he came to Allah's Messenger (SAW) and asked him (about that). Allah's Messenger (SAW) asked, "Did the place contain any idol which was worshiped (during Jahiliyya era)?" He said, "No." He asked "Were any of their (Jahiliyya) festivals observed there?" He said, "No." He then said (to the man), "Fulfill your vow, for there is no fulfillment of a vow to do an act of disobedience to Allah, now to break the ties of relationship, nor to do something over which a human being has no control." [Reported by Abu Dawud and at-Tabarani, and the wording is his (at-Tabarani). It has a sound chain of narrators].

"It was the custom among the Companions of Muhammad (SAW), that if any of them was fasting and the food was presented but he had slept before eating, he would not eat that night, nor the following day until the evening. Qais bin Sirmah Al-Ansari fasted and came to his wife at the time of Iftar, and said to her: 'No, but I will go and bring something for you.' He worked during the day, so his eyes (sleep) overcame him. Then his wife came, and when she saw him she said: 'You shall be disappointed.' About the middle of the next day he fainted. That was mentioned to the Prophet (SAW), so this Ayah was revealed: 'It is made lawful for you to have sexual relations with your women on the night of the fasts. So they were very happy about that. 'And eat and drink until the white thread (light) of dawn appears distinct to you from the black thread (of night). (2:187)'"

"The Messenger of Allah was never seen eating while reclining or making two men walk behind him." (Sahih) Other chains with the same meanings.

“The Messenger of Allah (saw) said the Salam after three Rak’ah for ‘Asr, then he stood up and went into the apartment. Khirbaq, a man with big hands, stood up and called out: ‘O Messenger of Allah! Has the prayer been shortened?’ He came out angrily, dragging his lower garment, and asked about it, and was told (what had happened). So he performed the Rak’ah that he had omitted, then he said the Salam, then he prostrated twice and said the Salam again.”

"The Messenger of Allah said: 'My Ummah will continue to adhere to the Fitrah so long as they do not delay the Maghrib until the stars have come out." (Hasan)Abu 'Abdullah bin Majah said: I heard Muhammed bin Yahya saying: 'The people in Baghdad were confused in narrating this Hadith. Abu Bakr Al-A'yan and I went to 'Awwam bin 'Abbad bin 'Awwam and he brought out to us the book of his father, and this Hadith was in it.'"

that the Messenger of Allah (SAW) said: "O you people! Indeed Allah is Tayyib (good) and he does not accept but what is good. And indeed Allah ordered the believers with what He ordered the Messengers. He (SAW) said: 'O you Messengers! Eat of the good things and do righteous deeds. Verily I am well acquainted with what you do (23:51).' And He said: 'O you who believe! Eat from the good things We have provided you (2:172).' He said: "And he mentioned a man: 'Who is undertaking a long journey, whose hair is dishevelled and he is covered with dust. He raises his hands to the heavens and says: "O Lord! O Lord!" Yet his food is from the unlawful, his drink is from the unlawful, his clothing is from the unlawful, and he was nourished by the unlawful. So how can that be accepted?'"
