Azraq bin Qays reported,

Ati said, I saw Ibn Umar, when he rose from the second rakah, press his hand against the ground for support.I asked his son and those sitting with him, "Perhaps he does this because of old age?"They replied, "No, but this is how it is done."

Hasan

عن الأزرق بن قيس قال

رأيت ابن عمر إذا قام من الركعتين اعتمد على الأرض بيده. فقلت لولده ولجلسائه: لعله يفعل هذا من الكبر؟ قالوا: لا ولكن هذا يكون.
