Surah al-Fajar (The Daybreak)
Recite this surah in your obligatory and supererogatory salats because it is related to Imam Hussain (A.S), so the reciter would be in the company of Imam Hussain (A.S) on the day of judgement and in paradise.
Moreover, ALLAH would forgive his sins equal in number to the reciters of this surah, and on the day of judgement a light would be with him. In this world he would remain in the protection of ALLAH for 24 hours after the recitation.
Whoso writes this surah on paper, and wears it around his neck as a tawiz and sleeps with his wife, ALLAH would give him a blessed and virtuous son who would be a source of comfort to him.
This written surah as a tawiz can also be put around the neck of the wife.
