Mafātīḥ al-jinān (Arabic: مفاتیح الجنان), (keys to the heavens) by Shaykh Abbas Qummi is the most popular book of supplication in the Shi'a world. It contains du'as, supplications, Ziyara texts, practices specific to certain days, months, and occasions, religious practices and manners, as well as some anecdotes narrated from the Prophet (s), Imams (a), and Islamic scholars.
Before Mafatih al-jinan, other du'a books were used by the Shi'ites. The compiler of Mafatih al-jinan has included content from other books including Iqbal al-a'mal by al-Sayyid b. Tawus, Misbah by al-Kaf'ami, and Zad al-ma'ad by al-'Allama al-Majlisi.
Mafatih al-jinan was very well received soon after it was published. Nowadays, it can be found in almost all houses, mosques, and Islamic centers.
