It is narrated from Sayyiduna Abu Musa Ash'ari (may Allah be pleased with him) that he was with the Prophet (peace and blessings of Allah be upon him) in one of the gardens of Madinah Tayyibah. The Prophet (peace be upon him) had a stick in his hand with which he was striking the soil and water. During this, a man came and asked for the door (of the garden's enclosure) to be opened. The Prophet (peace be upon him) said: "Open the door and give him the glad tidings of Paradise." I went and it was Sayyiduna Abu Bakr (may Allah be pleased with him). I opened the door and gave him the glad tidings of Paradise. Then another person asked for the door to be opened, so the Prophet (peace be upon him) said: "Open the door for him and give him the glad tidings of Paradise." I saw that it was Sayyiduna Umar (may Allah be pleased with him). I opened the door for him and gave him the glad tidings of Paradise. Then a third man requested for the door to be opened, and the Prophet (peace be upon him) was reclining, so he sat up and said: "Open the door for him and give him the glad tidings of Paradise after a calamity that will befall him in the future." I went and it was Sayyiduna Uthman (may Allah be pleased with him). I opened the door and conveyed the statement of the Prophet (peace be upon him). He said: Allah is the Helper.
