mafatih al jinan

Imam ‘Ali ibn al-Husayn Zayn al-’Abidin (‘a) used to gather all his companions at the beginning of Sha’ban and say to them, “O my companions, do you know what this month is? It is Sha’ban. The Holy Prophet (S) used to say, ‘Sha’ban is my month.’ You should thus fast during this month as a sign of your love for your Prophet (S) and as a sign of seeking nearness to your Lord. I swear by Him Who grasps my soul in His Hand that I heard my father Husayn (‘a), saying that he heard Imam ‘Ali, the Commander of the Faithful (‘a), saying: ‘Any one who fasts during Sha’ban for the love of the Messenger of Allah (S) to seek nearness to Almighty Allah, Almighty Allah will love him,and draw him nearer to Himself on the Day of Resurrection and definitely reward him with Paradise.
—  Imam Sadiq (a), Mafatih al-Jinan, pp. 154.

Shaykh Abbas al-Qummi is the author of the book of du’as called Mafatih al-Jinan, (Keys to the Heavens). He was an expert in hadith, and for this reason, he is famously known as Muhaddith-e Qummi. Amongst his many other works, Manazil-e Akhira and Safinatul-Bihar are well-known.

When he began to compile the Mafatih, some scholars of Qum advised him to use his vast knowledge to write explanatory notes on some of the complicated books instead, like Kifayah and Makasib of Shaykh al-Ansari.  “Are you just sitting writing a book of du’as?” they asked. He replied, “I will continue writing the Mafatih, and I have dedicated its reward to the soul of Fatima Zahra (AS), and, with her blessings, it will become Mafatih al-Jinan - keys to the gardens of Paradise.”

He was a man of great piety and a sincere lover of the Prophet (S) and his progeny (AS). Such was his faith and conviction, that one day, when his son was very ill, he took a glass of water, and after mixing the water with his finger, he gave it to his son to drink, saying, “Drink this my son, you will soon be better, because with this hand I have written many ahadith (traditions) of the Ahlu’l Bayt (AS).”
