On the year of the Battle of Tabuk, the Messenger of Allah ﷺ rose at night to pray. Some men from among his companions gathered behind him, standing guard over him. When he had finished his prayer and turned to them, he said, "Tonight I have been given five things that no one before me was given."He then recounted the lengthy hadith, and concerning the fifth he said, "As for the fifth, what a thing it is. I was told, 'Ask, for every prophet has asked.' So I deferred my request until the Day of Resurrection. It is for you and for everyone who bears witness that there is no god but Allah."
أن رسول الله ﷺ عام غزوة تبوك قام من الليل يصلي، فاجتمع وراءه رجال من أصحابه يحرسونه حتى إذا صلى وانصرف إليهم، فقال لهم: لقد أعطيت الليلة خمسا ما أعطيهن أحد قبلي. فذكر الحديث بطوله: والخامسة هي ما هي قيل لي: سل فإن كل نبي قد سأل، فأخرت مسألتي إلى يوم القيامة، فهي لكم ولمن شهد أن لا إله الا الله.
Imam Ahmad (7068) narrated it from Qutayba bin Saeed, who said, Bakr bin Mudar reported to us, from Ibn Hadi, from Amr bin Shuayb, from his father, from his grandfather, and he mentioned it. Its chain is hasan because of Amr bin Shuayb, for he is hasan al-hadith.Haythami said in Majmaa (10/367), "Ahmad narrated it, and its narrators are trustworthy."
