I said to Ayesha, "Umm Muiminin, there are people who recite the entire Quran twice or three times in a single night."She replied, "Those people have recited, yet they have not truly recited. The Messenger of Allah ﷺ used to stand in prayer through an entire night, reciting Surah al-Baqarah, Surah Al Imran, and Surah an-Nisa. He would not pass by a verse containing glad tidings without calling upon Allah and longing for it, nor pass by a verse containing a warning without calling upon Allah
and seeking refuge with Him."
قلت لعائشة: يا أم المؤمنين إن ناسا يقرأ أحدهم القرآن في ليلة مرتين، أو ثلاثا، فقالت: أولئك قرؤوا، ولم يقرؤوا، كان رسول الله ﷺ، يقوم الليلة التمام، فيقرأ سورة البقرة، وسورة آل عمران، وسورة النساء، ثم لا يمر بآية فيها استبشار إلا دعا الله عز وجل ورغب، ولا يمر بآية فيها تخويف إلا دعا الله عز وجل واستعاذ.
Ahmad narrated it (24875) from Ali bin Ishaq, who said, Abdullah told us, who said, Ibn Lahia told us, from Harith bin Yazid, from Ziyad bin Nuaym Hadrami, from Muslim bin Mikhraq, and he related it.Its isnad is hasan, because of Ibn Lahia, due to Abdullah bin Mubarak's narration from him, and because of Muslim bin Mikhraq, who is a freedman of Ayesha, even though no one but Ibn Hibban rated him trustworthy. Moreover, his hadith has sahih corroborating narrations concerning lengthening the recitation in night prayer, which are documented in their proper places. However, some scholars of knowledge permitted completing the Quran in a single night, reciting it all in one rakat, as was reported from Uthman bin Affan.Ibn Abu Shayba narrated it in his Musannaf (8678), from Yazid bin Harun, from Muhammad bin Amr, from Muhammad bin Ibrahim, from Abdul-Rahman bin Uthman, who said, "I stood behind the Maqam praying, wanting to make sure that no one would surpass me that night. Then a man behind me nudged me, but I did not turn toward him. He nudged me again, so I turned, and there was Uthman bin Affan. I moved aside and he stepped forward and recited the entire Quran in one rakat, then left." Its isnad is hasan.It was also reported similarly from Tamim Dari, as found in Ibn Abu Shayba (8677), though its isnad has a break.Perhaps Uthman bin Affan did that once or twice, since the basic rule is that it is not permissible to complete the Quran in less than three days.As for the longest period allowed for completing the Quran, Abu Hanifa held that whoever recites the Quran twice every year has fulfilled its due, because the Prophet ﷺ presented it to Jibreel twice in the year in which he died.Ahmad said, "The most I have heard is that the Quran be completed within forty days, because delaying it beyond that leads to forgetting the Quran and being negligent toward it, so what we have mentioned is preferable." This applies when there is no excuse, but with an excuse there is latitude for him. Mughni (2/611–612).That is, referring to one occupied with governance, judgeship, knowledge, and the like. He may shorten or lengthen this period, and all of it is valid.As for gathering and supplicating upon completing the Quran, some of the early generations permitted it. Tabarani reported in al-Kabir (1/242), with his isnad, from Anas, that when he completed the Quran he would gather his family and supplicate.Haythami said in Majma (7/172), "Its narrators are trustworthy."I say, it was also reported from Qatada from Anas as a raised narration, but this is a mistake, and its isnad contains unknown narrators, as Bayhaqi said in Shuab al-Iman (3/422).And from Mujahid, who said, "They used to gather upon the completion of the Quran, saying, 'At that moment mercy descends.'"
