The Book of Prayers
كتاب الصلاة
Read the English translation first, with the original Arabic directly underneath.
If The Imam Experiences An Excuse, From Illness, Or Travelling, Etc. He May Appoint Someone Else To Lead The People In Prayer; The One Who Offers Prayer Behind The Imam Sitting Because He Is Unable To Stand Must Stand If He Is Able To Do So; And The Abrogation Of Sitting Behind A Sitting Imam For Those Who Are Able To Stand
Suhail reported that his father sent him to Banu Haritha along with a boy or a man. Someone called him by his name from an enclosure. He (thenarrator) said:
The person with me looked towards the enclosure, but saw nothing. I made a mention of that to my father. He said: If I knew that you would meet such a situation I would have never sent you (there), but (bear in wind) whenever you hear such a call (from the evil spirits) pronounce the Adhan. for I have heard Abu Huraira say that the Messenger of Allah (may peace be upbn him) said: Whenever Adhan is proclaimed, Satan runs back vehemently.
إِنَّ الشَّيْطَانَ إِذَا نُودِيَ بِالصَّلاَةِ وَلَّى وَلَهُ حُصَاصٌ
