67 - Muhammad informed us, saying: Waki' informed us, from Muhammad ibn Qays, from Musa ibn Tarif, who said: A man came to 'Ali and said: 'Inform me of a good that I may follow, or an evil that I may avoid.' 'Ali, may Allah be pleased with him, said: 'Bakh, bakh (excellent, excellent)! You have expressed something momentous, extensive, and concise. Show me your hand.' He gave him his hand, and 'Ali said: 'Do not ever break your pledge, do not ever depart from your leaders, and do not ever revert to being a bedouin after your migration. Take it, short and long, just as you have given it to me, short and long.'
