11. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa from al-Hassan ibn Ali ibn ‘Uqbah from abu Kahmas who has said the following:

“A man once asked ‘Abd Allah ibn al-Hassan to teach him something for increased sustenance. He said, ‘Remain in the place of your Salat (prayer) after the morning Salat (prayer) until sunrise; it is more useful for seeking increased sustenance than traveling in the land.’ I informed abu ‘Abd Allah , about it and he (the Imam) said, ‘Will you like if I teach you for increased sustenance what is more useful than that?’ I replied, ‘Yes, I will like it.’ He (the Imam) said, ‘Clip your fingernails and mustache every Friday.’”
