Abu Bakr bin Abdullah bin Abi Maryam narrates that Abdullah bin Abi Qais narrated a hadith to me from the Mothers of the Believers, they informed that Allah Almighty gave special guidance to His Prophet, so he asked the Mothers of the Believers to tell him about that guidance which Allah had given to His Prophet. Thus, they said, Allah Almighty had guided His Prophet regarding the standing in the night (Qiyam al-Lail).
