Jami at-Tirmidhi Hadith 3430

Al-Agharr Abu Muslim narrated that he bears witness from Abu Sa’eed Al-Khudri and Abu Hurairah, that they bear witness that : the Prophet (ﷺ) said: “Whoever says: ‘There is none worthy of worship except Allah, and Allah is the Greatest, (Lā ilāha illallāh, wa Allāhu akbar)’ His Lord affirms his statement and says: ‘There is none worthy of worship except Me, and I am the Greatest,’ and when he say: ‘There is none worthy of worship except for Allah, Alone, (Lā ilāha illallāh, waḥdahu)’ Allah says: ‘There is none worthy of worship except for Me and I am Alone.’ And when he say: ‘There is none worthy of worship except for Allah, Alone, without partner, (Lā ilāha illallāh, waḥdahu lā sharīka lahu)’ Allah says: ‘There is none worthy of worship except Me, Alone, I have no partner.’ And when he say: ‘There is none worthy of worship except for Allah, to Him belongs all that exists, and to Him is the praise, (Lā ilāha illallāh, lahul-mulku wa lahul-ḥamdu)’ Allah says: ‘There is none worthy of worship except Me, to Me belongs all that exists, and to Me is the praise.’ And when he says: ‘There is none worthy of worship except Allah, and there is no might or power except by Allah, (Lā ilāha illallāh, wa lā ḥawla wa lā quwwata illā billāh)’ Allah says: ‘There is none worthy of worship except Me, and there is no might or power except by Me.’” And he used to say: “Whoever says it in his illness, then dies, the Fire shall not consume him.”
