It is narrated from Hazrat Abu Musa (may Allah be pleased with him) that once we were on a journey with the Noble Prophet (peace and blessings be upon him). We ascended a valley, and after describing its terrors, he said that people began to say takbeer and tahlil. The Noble Prophet (peace and blessings be upon him) said: O people! Be gentle with yourselves, for the people had raised their voices. O people! You are not calling upon a deaf or absent Allah; He is with you at every moment.
