It is narrated from Aswad and Alqamah that: Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) said: When any of you performs ruku‘, he should spread his arms over his thighs and bend his back. Then he interlaced his fingers and said: It is as if I am seeing the fingers of the Messenger of Allah (peace and blessings be upon him) that they were interlaced with each other. Then he interlaced his fingers and showed them.
