2 million good deeds (dua-prayer)
Holy Prophet Mohammed (Sallallaho Alaihi Wa’Sallam) has said, that whoever recites these kalimats 2 Million good deeds will be written down in his/her book of good deeds. During Ramadan the sawab/reward increases 70 times.
During Ramadan 1 time reciting of it will cause 140 Million (14 Crore) good deeds written down in his/her book of good deeds. The more you recite it, the more you will get sawab/reward.
