Yahya related to me from Malik from Ibn Shihab from Sulayman ibn Yasar that the people of Syria said to Abu Ubayda ibn al-Jarrah, "Take zakat from our horses and slaves," and he refused. Then he wrote to Umar ibn al-Khattab and he (also) refused. Again they talked to him and again he wrote to Umar, and Umar wrote back to him saying, "If they want, take it from them and (then) give it back to them and give their slaves provision."

Malik said, "What he means, may Allah have mercy upon him, by the words 'and give it back to them' is, 'to their poor.' "

Yahya related to me from Malik that Zayd ibn Aslam had said that Ubayda ibn al-Jarrah had written to Umar ibn al-Khattab mentioning to him a great array of Byzantine troops and the anxiety they were causing him. Umar ibn al-Khattab wrote in reply to him, "Whatever hardship befalls a believing slave, Allah will make an opening for him after it, and a hardship will not overcome two eases. Allah the Exalted says in His Book, 'O you who trust, be patient, and vie in patience; be steadfast and fear Allah, perhaps you will profit.' " (Sura 3 ayat 200).

This hadith has been transmitted on the authority of Ibn Abu Aufa with a slight variation of words.

Abu Hurairah said “When the Prophet (saws) entered Makkah he left Al Zubair bin Al Awwam, Abu ‘Ubaidah bin Al Jarrah and Khalid bin Al Walid on the horses and he said “Abu Hurairah call the helpers.” He said”Go this way. Whoever appears before you kill him”. A man called “the Quraish will be no more after today.” The Apostle of Allaah(saws) said “he who entered house is safe, he who throws the weapon is safe. The chiefs of the Quraish intended (to have a resort in the Ka’bah), they entered the Ka’bah and it was full of them. The Prophet (saws) took rounds of Ka’bah and prayed behind the station. He then held the sides of the gate (of the Ka’bah). They (the people) came out and took the oath of allegiance (at the hands) of the Prophet (saws) on Islam.

Abu Dawud said “I heard Ahmad bin Hanbal (say) when he was asked by a man “Was Makkah captured by force?” He said “What harms you whatever it was? He said “Then by peace?” He said, No.

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.'
