It is narrated from Sayyiduna Ubayd bin Umair (may Allah be pleased with him) that on the day of Badr, out of a sense of covering their brothers, the Muslims placed them in a well. Then the Messenger of Allah (peace and blessings be upon him) came and stood over them and said: "O so-and-so! O so-and-so! Did you not find Allah true to His promise? O so-and-so! O so-and-so!" He (peace and blessings be upon him) would call them by their names, then said: "Did you not find Allah true to His promise?" The companions said: "O Messenger of Allah (peace and blessings be upon him), do they hear?" He said: "By the One in Whose hand is my soul! They hear just as you hear."
