It is narrated from Sayyidah Umm Salamah (may Allah be pleased with her) that the Prophet (peace and blessings be upon him) prayed two rak'ahs after Asr in her house, which he had not prayed before that, nor did he pray them after that.

It is narrated from Sayyidah Umm Salamah (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) said: "Allegiance will be pledged to a man between the Rukn and the Maqam by people equal in number to those who were at Badr. Then bands of the people of Iraq and the Abdal of the people of Syria will come to him. Then an army from the people of Syria will come to fight them, until, when they reach al-Bayda', they will be swallowed up by the earth. A man of Quraysh whose maternal uncles are from the tribe of Kalb will come to fight against him; the two armies will meet, and he will defeat them." So it used to be said: The loser is the one who misses out on the spoils of Kalb.
