Anas bin Malik reported,
I was sitting with the Messenger of Allah ﷺ in the circle when a man came and greeted the Prophet ﷺ and the people, saying, "Peace be upon you."The Prophet ﷺ returned the greeting, "And upon you be peace, and the mercy of Allah and His blessings."When the man sat down, he said, "All praise is due to Allah, abundant, pure, and blessed praise, as our Lord loves and is pleased with."The Prophet ﷺ asked him, "How did you say it?"The man repeated to the Prophet ﷺ what he had said.The Prophet ﷺ then said, "By the One in whose hand my soul is, ten angels rushed to record it, each eager to write it down, but they did not know how to write it, so they took it up to the Lord of Might, who said, 'Write it down as My servant said it.'"
Azami 279
Hasanعن أنس قال
كنت جالسا مع رسول الله ﷺ في الحلقة إذ جاء رجل فسلم على النبي ﷺ وعلى القوم، فقال: السلام عليكم، فرد عليه النبي ﷺ: وعليكم السلام ورحمة الله وبركاته. فلما جلس الرجل قال: الحمد لله كثيرا طيبا مباركا فيه كما يحب ربنا ويرضى. فقال له النبي ﷺ: كيف قلت؟ فرد على النبي ﷺ كما قال، فقال النبي ﷺ: والذي نفسي بيده لقد ابتدرها عشرة أملاك كلهم حريص على أن يكتبوها، فما دروا كيف يكتبونها حتى رفعوه إلى ذي العزة فقال: اكتبوها كما قال عبدي.
Nasai narrated it in Amal al-Yawm wal-Layla (341) from Qutayba bin Saeed, who said, Khalaf narrated to us, from the nephew of Anas, from Anas, and he related it. Its chain is hasan because of Khalaf, who is Ibn Khalifa bin Sad al-Ashjai, their freedman, al-Wasiti, and he is hasan al-hadith. Ibn Adi said, "I hope there is no harm in him, though I cannot clear him of erring in some hadiths in some of his narrations." I say, he became confused in his later years, and Muslim included a narration from him through Qutayba. Ibn Hibban graded it sahih (845), and Diya in al-Mukhtara (1887), both from the hadith of Qutayba bin Saeed, with the same wording, similarly. Imam Ahmad also recorded it (12612) through another route from Khalaf with his chain, similarly.As for what has been narrated through a different route from Anas, that the man who said that during prayer, as will come later, does not contradict what Khalaf narrated, since this can be reconciled by assuming multiple occurrences. The nephew of Anas is Hafs bin Umar, as appears in the narration of Imam Ahmad, so he is Hafs bin Umar bin Abdullah bin Abu Talha, the nephew of Anas through his mother, and he is "truthful." Hakim graded a hadith of his as sahih (1/503), as will come later in the chapter on prayer, on the criterion of Muslim, but this was a mistake, for this nephew of Anas was not narrated from by Muslim. Rather, Abu Dawud, Tirmidhi, and Bukhari in Adab al-Mufrad narrated from him, as indicated by Hafiz's symbol for him in Taqrib.
