It was narrated that Saad bin Hisham said: “I said: ‘Mother of the Believers! Tell me about theWitrof the Messenger of Allah صلی اللہ علیہ وآلہ وسلم .‘ She said: ‘We used to prepare his Siwak and water for purification, then Allah would wake him when He willed to wake him at night. He would use the Siwak and perform Wudu’, then pray eight Rak’ahs; not sitting until the eighth Rak’ah, when he would sit and remember Allah and call upon Him. Then he would say the Taslimloud enough for us to hear.” (Sahih)
