For The Lack of Children

Ahmad b. ‘Imran b. Abu Layla narrated from ‘Abd al-Rahman b. Abu Najran from Sulayman b. Ja’far al-Ja’fari from Abu Ja’far the first, al-Baqir b. ‘Ali b. al-Husayn b. ‘Ali, peace be upon him, that a man complained to him of lack of children. He had tried for a chiid from bondmaids and free-born women (al-hara’ir), but it was not granted to him and he was now sixty years old. He [al-Baqir] said: ‘For three days after your obligatory evening prayer (al-‘isha’) and after the morning prayer, recite: "Glory be to Allah," seventy times; “I ask for forgiveness from Allah”, seventy times; and end it with the statement of Allah, the Mighty and Sublime:

Ask forgiveness of your Lord. Surely He is ever All-forgiving, and He will loose heaven upon you in torrents and will succour you with wealth and sons, and will appoint for you gardens, and will appoint for you rivers (71:10-12). Then have intercourse with your wife on the third night and you will be blessed, Allah willing, with a healthy boy.’

He [the man] said: 'I did that and the year was not over when I was blessed with a child.’
