It has been reported on the authority of Anas b. Malik who said: The Messenger of Allah ﷺ sent Busaisah as a scout to see what the caravan of Abu Sufyan was doing. He came (back and met the Holy Prophet in his house) where there was nobody except myself and the Messenger of Allah. I do not remember whether he (Hadrat Anas) made an exception of some wives of Prophet ﷺ or not and told him the news of the caravan. (Having heard the news), the Messenger of Allah ﷺ came out (hurriedly), spoke to the people and said: We are in need (of men) ;
whoever has an animal to ride upon ready with him should ride with us. People began to ask him permission for bringing their riding animals which were grazing on the hillocks near Medina. He said: No. (I want) only those who have their riding animals ready. So the Messenger of Allah ﷺ and his Companions proceeded towards Badr and reached there forestalling the polytheists (of Mecca). When the polytheists (also) reached there, the Messenger of Allah ﷺ said: None of you should step forward to (do) anything unless I am ahead of him. The polytheists (now) advanced (towards us), and the Messenger of Allah ﷺ said. Get up to enter Paradise which is equal in width to the heavens and the earth. 'Umair b. al- Humam al-Ansari said: Messenger of Allah, is Paradise equal in extent to the heavens and the earth? He said: Yes. 'Umair said: My goodness! The Messenger of Allah ﷺ asked him: What prompted you to utter these words (i. e. my goodness! ')? He said: Messenger of Allah, nothing but the desire that I be among its residents. He said: Thou art (surely) amona its residents. He took out dates from his bag and began to eat them. Then he said: If I were to live until I have eaten all these dates of mine, it would be a long life. (The narrator said): He threw away all the dates he had with him. Then he fought the enemies until he was killed.
