Hazrat Abdullah bin Shaqiq narrates from Sayyidah Aisha (may Allah be pleased with her) that she said, the Messenger of Allah (peace and blessings be upon him) used to stand for a long time at night and offer prayer. Therefore, when he (peace be upon him) prayed standing, he would also perform ruku‘ standing, and when he (peace be upon him) prayed sitting, he would also perform ruku‘ sitting.
