“Once a man came to abu ‘Abd Allah (a.s.), and said, ‘I am not good in working with my hands and I am not good in doing business, thus I am deprived and needy.’ He (the Imam) said, ‘You must work and carry it on your head and set yourself free from asking people for help. The Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, carried a stone on his shoulder to place it in a certain place of his walls. The stone is still in its place, and it is not known how large it is, but it is there [by his miracle]”’
