In The Name of Allah, The Most Merciful, The Bestower of Mercy.

Shaikh al-Islam Ibn Taymiyyah, may Allah have mercy upon him, said: “It is well-known that Malik, may Allah have mercy upon him, disliked that the supplicant says: ‘ياسيدي سيدي’. He said, “Say as the prophets said: ‘يارب يارب ياكريم’. He also disliked that it is said: ‘ياحنان يامنان’ as this is not reported from him.

Al-Allamah Rabee Bin Hadi Al-Mad’khali, may Allah have mercy upon hi, briefly commented:

As for al-Mannān, it has been reported in the hadith whose wording is:

اللهم إني أسألك بأن لك الحمد لا إله إلا أنت المنان بديع السماوات والأرض ياذا الجلال والإكرام ياحي ياقيوم

O Allah! I ask You by virtue of the fact that all praise is due to You; none has the right to be worshiped but You alone, al-Mannān (The Beneficent Bestower of Bounties. The One such that all favors and blessings originate from Him. He is The One Who granted them and favored the creation with them), (1) the Originator of the heavens and the earth, the Possessor of Majesty and Honour.

This narration was reported by Abu Dawood in the (Book) of Prayer Hadith (1495), by Al-Tirmidhi in the (Book) of supplications Hadith (3544), by Al-Nasa’i, Hadith (1300), and by Ibn Majah in the (Book) of supplications Hadith (3858). All of these are transmitted through various chains from Anas, and their collective authenticity supports the narration. Al-Albani declared it authentic; see: Sahih Abu Dawood, number (1325). As for al-Ḥannān, it was narrated by Al-Tabarani in Al-Awsat with a weak chain. See: Majma’ Al-Bahrain, Hadith (4639). The statement: “It is not reported” means that it is not reported in this manner. [paraphrased]

هل ثبت اسم المنان والحنان لله تعالى؟

(1) al-Mannān: (The Beneficent Bestower of Bounties. The One such that all favors and blessings originate from Him. He is The One Who granted them and favored the creation with them). [Translated by Shaikh Abu Talhah dawud Burbank, may Allah have mercy upon him and his wife]
