"What is the hadith which Jabir bin `Abdullah (may Allah be pleased with him) narrated regarding saying Allahu--Akbar and Subhan Allah when ascending or descending places?"
 Narrated Jabir bin `Abdullah:                     Whenever we went up a place we would say, "Allahu--Akbar (i.e. Allah is Greater)", and whenever we went down a place we would say, "Subhan Allah."
