"If he turns over during a portion of the night and asks Allah for something of the good of this world and the Hereafter, Allah will grant it to him." (1)

This is a good (ḥasan) hadith. (2)

--------------------------------------------
(1) A sound ḥadīth by virtue of corroborating evidence (ṣaḥīḥ li-ghayrihi), but this chain of transmission is weak. Shahr ibn Ḥawshab is weak, and Ismāʿīl ibn ʿAyyāsh al-Ḥimṣī is unreliable in his narration from non-Syrian scholars, and this is one such case, for his shaykh ʿAbd Allāh ibn ʿAbd al-Raḥmān ibn Abī Ḥusayn is a Meccan. Moreover, there is disagreement concerning it from Shahr ibn Ḥawshab, as will follow.

It was also narrated by al-Ṭabarānī in "al-Kabīr" (7568), and Ibn al-Sunnī in "ʿAmal al-Yawm wa al-Laylah" (719) via multiple chains from Ismāʿīl ibn ʿAyyāsh, with this chain of transmission.

It was also narrated by Ibn ʿAdī in "al-Kāmil" 2/640 via the route of Ḥakīm ibn Nāfiʿ al-Raqqī, from al-Aʿmash, from Shimr, from Shahr, from Abū Umāmah. And Ḥakīm ibn Nāfiʿ al-Raqqī is weak.

Shahr ibn Ḥawshab also related it from Abū Ẓabyah al-Sulafī (with a ḍammah on the sīn, a relative attribution to Sulaf: a sub-tribe of Kalāʿ, and Kalāʿ is a sub-tribe of Ḥimyar), from ʿAmr ibn ʿAbasah, as the author mentioned immediately following the ḥadīth, and its full citation will follow.

It was also related from Abū Ẓabyah, from Muʿādh ibn Jabal, narrated by Aḥmad (22048), (22092), and (22114), Abū Dāwūd (5042), Ibn Mājah (3881), and al-Nasāʾī in "ʿAmal al-Yawm wa al-Laylah" (805) and (806).

It has another sound route from Muʿādh ibn Jabal, narrated by Aḥmad (22048), (22049), and (22092), Abū Dāwūd (5042), and al-Nasāʾī in "ʿAmal al-Yawm wa al-Laylah" (805) and (806) via the route of Ḥammād ibn Salamah, from Thābit al-Bunānī, from Abū Ẓabyah, from Muʿādh.

(2) In the printed edition it appears as: "good and strange" (ḥasan gharīb), while what is confirmed here is from our manuscript copies except (l), and from "Tuḥfat al-Ashrāf" 4/172. In (l) it reads: "strange ḥadīth" (gharīb) only.
