Silsilat al-Ahadith al-Sahihah

Azraq bin Qais says: I saw Sayyiduna Abdullah bin Umar (may Allah be pleased with him) that he would support himself with his hands to stand up in prayer. I said: Abu Abdur Rahman! What is this manner? He said: I saw the Messenger of Allah (peace and blessings be upon him) that he too would support himself with his hands to stand up in prayer.
