- " لا ينظر الله عز وجل إلى صلاة عبد لا يقيم فيها صلبه بين ركوعها وسجودها ".
It is narrated from Sayyiduna Taliq bin Ali (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "Allah, the Exalted, does not look towards the prayer of that servant in which he does not straighten his back during bowing and prostration."
