It is stated in a hadîth: “Good news to those on whose pages there are many istighfârs on the Day of Last Judgment!” [Muhammad Ma’thûm-i Fârûqî, in the eightieth letter of the second volume, states: “It has become a proven fact after a number of events experienced by various people that saying istighfârs is effective in getting rid of calamities and hardships. It has been reported in a hadîth-i sherîf that saying istighfâr causes every sort of adversity to be removed and one’s sustenance to increase. After each fard namâz it must be said three times, and this number, (three,) must be complemented to seventy by saying its abbreviated form, ‘Astaghfirallah.’ (sixty-seven times).”
