Ibn Hibban

Abdullah bin Shaqiq narrates: I asked Sayyida Aisha (may Allah be pleased with her) about the prayer of the Prophet (peace be upon him): She said: The Prophet (peace be upon him) used to perform four rak‘ahs before Zuhr, then he would go and perform the (obligatory) prayer. Then he would return and perform two rak‘ahs, then he would go for the Maghrib prayer, then he would return and perform two rak‘ahs. Then he would go for the ‘Isha prayer, then he would return and perform two rak‘ahs. Then at night he used to perform nine rak‘ahs. I asked: Did he perform these sitting or standing? Sayyida Aisha (may Allah be pleased with her) said: At night he used to perform long prayers standing. I asked: When he recited standing (how did he perform ruku‘)? Sayyida Aisha (may Allah be pleased with her) replied: When he recited standing, he would go into ruku‘ standing, and when he recited sitting, he would perform ruku‘ sitting. After that, he would perform two rak‘ahs (sunnah) before Fajr.
