Answered by Sayyidi Habib Umar bin Hafiz (may Allah protect him and benefit us by him)
Surat al-Fatihah is one of the best awrad for the seeker. It is good if it can be recited 40 or 41 times a day. Doing so is a means of removing affliction and fulfilling one’s needs. Even better is reciting it 100 times a day. It can be either be read at one time standing facing the qiblah, or it can be apportioned over the five prayers as follows: 21 times after Fajr, 22 times after Zuhr, 23 times after Asr, 24 times after Maghrib, and 10 times after Isha. If you are unable to complete the appointed number at the specific time you can make it up after the next prayer. Imam al-Ghazali and many knowers of Allah mention this method. Imam al-Haddad composed a dua to be read after this recitation.[1]
