al-Daylamī (1/1/31) reported from Muḥammad ibn ʿAbd Allāh ibn Ṣāliḥ al-Marwazī, who narrated to us from Bakr ibn Khudāsh, from Fiṭr ibn Khalīfah, from Abū Ṭufayl, from Abū Bakr al-Ṣiddīq as a marfūʿ ḥadīth. The ḥadīth was left ungraded by the ḥāfiẓ, and Bakr ibn Khudāsh was mentioned by Ibn Abī Ḥātim (1/1/385) with two other narrators from him, without any criticism or endorsement. The ḥāfiẓ also mentioned him in "al-Lisān" with reports from several others and said: "He sometimes contradicted." Ibn Ḥibbān mentioned this in "al-Thiqāt." As for Muḥammad ibn ʿAbd Allāh ibn Ṣāliḥ al-Marwazī, I do not know him. Al-Sakhāwī said about the ḥadīth in "al-Qawl al-Badīʿ" (p. 117): "It was reported by al-Daylamī, and its chain is weak." However, he mentioned a supporting narration from the ḥadīth of ʿAmmār ibn Yāsir (raḍiya Allāhu ʿanhu) who said: The Messenger of Allāh (ṣallá Allāhu ʿalayhi wa-sallam) said: "Indeed, Allāh has an angel who has been given the hearing of all creatures, and he stands by my grave. When I die, no one sends prayers upon me except that he says: 'O Muḥammad, so-and-so son of so-and-so has prayed upon you.' Then the Lord blesses that person tenfold for each prayer." He also said (p. 112): "It was narrated by Abū al-Shaykh ibn Ḥayyān, Abū al-Qāsim al-Taymī in 'Targheeb' (209/2 - Madīnah), al-Ḥārith in 'Musnad,' Ibn Abī ʿĀṣim, al-Ṭabarānī in 'al-Muʿjam al-Kabīr,' Ibn al-Jarrāḥ in 'Amālī,' in similar terms, Abū ʿAlī al-Ḥasan ibn Naṣīr al-Ṭūsī in 'Aḥkām,' and al-Bazzār in 'Musnad.' In the chain of all of them is Naʿīm ibn Ḍamḍam, and there is disagreement about ʿImrān ibn al-Ḥumayrī. Al-Mundhirī said: 'He is unknown.'" I say: Rather, he is known, and al-Bukhārī considered him weak, saying: "He is not followed up on." Ibn Ḥibbān mentioned him in "Thiqāt al-Tābiʿīn," said the author of "al-Mīzān."
