Khatm Of Qur'an Al-Karim

Imam-i Birgivi (rahmatullahi 'aleyh) says in his book Atfal-ul muslimin: 

A tradition (conveyed by savants) declares,"The number of the grades in Paradise is the same as the number of the ayats (verses) in Qur'an al-karim. A person who does a khatm [1] of Qur'an al-karim will attain to all those grades. " A hadith-i sharif [2], which exists in Kunuz-ud deqaiq and which is transmitted by Tabarani and Ibn Hibban, declares, "The prayer of a person who does a khatm of Qur'an al-karim is acceptable. " It is written in Kitab-ut tibyan, "Rahma (Allah's mercy and compassion) rains on a place where the khatm of Qur'an al-karim is performed. It is mustahab [3] to say prayers after a khatm. It is mustahab to assemble when doing khatm of Qur'an al-karim. Hadrat [4] Abdullah ibn Abbas would have one of his men keep company with the person doing a khatm. And he himself would join them when the khatm was finished. Hadrat Enes bin Malik would gather his household together and pray whenever he did a khatm.

It is mustahab to begin another khatm when one khatm is over. A hadith-i sharif declares, "The best of worships is to begin a new khatm when one khatm is over. " Hadiths, which exist in Hazinat-ul esrar, declare, "Sixty thousand angels pray for a person who does a khatm of Qur'an al-karim,"and, "A person who attends a place where they are doing the prayer of khatm is like a person who is present while the ghanima is being divided and distributed. A person who is present at the place where they begin a khatm is like one who makes jihad. A person who attends both attains the thawabs for both and thus thwarts the Shaytan. "

Sa'd ibn Abi Waqqas said, "If a person reads (a passage from Qur'an al-karim) for a khatm during the day, angels pray for him till evening. If he does so at night, they pray for him till morning. "
