4. A number of our people have narrated from Ahmad ibn Muhammad ibn Khalid from ‘Uthman ibn ‘Isa from Sama‘ah ibn Mehran who has said the following:

“I once asked abu ‘Abd Allah , about the case of a man who sleeps in a house alone. He (the Imam) said, ‘I dislike it but if it is an emergency, then it is not harmful, however, he must speak of Allah a great deal and as much as he can, when he goes to sleep.’”
