The Messenger of Allah ﷺ said, "There is a surah in the Quran consisting of only thirty verses which interceded on behalf of its companion until it brought him into Paradise. It is Surah Tabarak."
قال رسول الله ﷺ: سورة من القرآن ما هي إلا ثلاثون آية، خاصمت عن صاحبها حتى أدخلته الجنة، وهي سورة تبارك.
Tabarani related it in Al-Awsat (3667) and in Al-Saghir (490) from Sulayman bin Dawud bin Yahya Tabib Basri, who said, Shayban bin Farroukh told us, who said, Salam bin Miskin told us, from Thabit Bunani, from Anas bin Malik, who said, and then he mentioned it.Haythami said in Majma (8/127), "Tabarani related it in Al-Saghir and Al-Awsat, and its narrators are the narrators of the Sahih."I say, its chain is hasan because of Shayban bin Farroukh, for he is hasan al-hadith, and Ibn Hajar graded it sahih in Talkhis (1/235), considering that Shayban is among the narrators of the Sahih.
