It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that some of the noble companions (may Allah be pleased with them) complained to the Holy Prophet (peace and blessings be upon him) that when they are broad (in body), it becomes difficult for them to perform prostration. The Holy Prophet (peace and blessings be upon him) said: Take support from your knees. The narrator of the hadith, Ibn ‘Ajlan, says that when the prostration becomes prolonged and a person becomes tired, he should place his elbows on his knees.
