“I once asked abu ‘Abd Allah , about a man who has said, ‘It is from Allah upon me to fast a Hin (a certain amount of time) for thanksgiving.’ Abu ‘Abd Allah , said, ‘A similar case came to Ali , and he said, ‘Fast for six months; Allah, most Majestic, most Glorious, has said, ‘It gives its fruits kulla Hin by the permission of its Lord’, that is six months.’”
