Tirmidhi

´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.”

´It was narrated from Abu Hurairah and Abu Saeed bore witness that the Messenger of Allah(ﷺ) said:` "If a person says: 'La ilaha illallahu wa Allahu Akbar (None has the right to be worshipped but Allah and Allah is the Most Great),'Allah says: 'My slave has spoken the truth; there is none worthy of worship except I, and I am the Most Great.' If a person says: La ilaha Illallah wahdahu (There is none worthy of worship except Allah alone), Allah says: 'My slave has spoken the truth; there is none worthy of worship except I, alone.' If he says, La ilaha illallahu la sharikalahu (There is none worthy of worship except Allah with no partner or associate),' Allah says: 'My slave has spoken the truth; there is none worthy of worship except I, with no partner or associate.' If he says: 'La illah illallah, lahul mulku wa lahul hamdu (There is none worthy of worship except Allah, all dominion is His and all praise is to Him),' Allah says: 'My slave has spoken the truth; there is none of worthy of worship except I, all dominion Mine and all praise is due to Me.' If he says: ' La illaha illallah, la hawla wa la quwwata illa billah (There is none worthy of worship and there is no power and no strength except with Allah),' Allah says: 'My slave has spoken then truth; there is none worthy of worship except I, and tehre is no power and no strength except with Me.' One of the narrators Abu Ishaq said: "Then Agharr (another narrator) said something that I did not understand. I said to Abu Jafar: 'What did he say?' He said: 'Whoever is blessed with (the ability to say) them (these words) at the time of death, the Fire will not touch him.'"
