It is narrated from Sayyiduna ‘Ubada bin Samit (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said:“Whoever bears witness that Allah alone is the true deity, He is One, He has no partner, and that Muhammad (peace and blessings be upon him) is His servant and His Messenger, and that ‘Isa (peace be upon him) is Allah’s servant and His Messenger and His word which He cast to Maryam (peace be upon her), and a spirit from Him, and that Paradise is true and Hell is true, then whatever his deeds may be, Allah Almighty will admit him into Paradise.”In another narration:“He will enter Paradise through whichever of its eight gates he wishes, Allah Almighty will admit him through that gate.”

It is also narrated from Sayyiduna ‘Ubada bin Samit (may Allah be pleased with him) that I heard the Messenger of Allah (peace and blessings be upon him) say:“Whoever bears witness that Allah alone is the true deity and that Muhammad (peace and blessings be upon him) is His Messenger, then he will be made forbidden for the Fire.”In another narration:“Allah will make the Fire forbidden for him.”

It is narrated from Sayyiduna Abdullah bin Salam (may Allah be pleased with him), he says: We were walking with the Messenger of Allah (peace and blessings be upon him) when he heard people saying: "O Messenger of Allah! Which deed is the most virtuous?" The Prophet (peace and blessings be upon him) said: "To have faith in Allah and His Messenger, to strive in the path of Allah, and Hajj Mabroor (an accepted pilgrimage)." Then a voice was heard from the valley, someone was saying: «أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللَّهُ وَأَنَّ مُحَمَّدًا رَسُولُ اللَّهِ» . Upon hearing this, the Messenger of Allah (peace and blessings be upon him) said: "And I also bear this testimony, and I also bear witness that whoever gives this testimony will be free from shirk (associating partners with Allah)." Imam Ahmad's son, Abdullah bin Ahmad, said: I heard this hadith directly from the narrator Haroon.

It is narrated from Sayyiduna Abu Ayyub Ansari (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever dies in such a state that he does not associate anyone with Allah Almighty, he will enter Paradise."

Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him) also narrated a similar hadith from the Noble Prophet (peace and blessings be upon him).

It is narrated from Sayyiduna Suhail bin Bayda’ (may Allah be pleased with him), he says: We were on a journey with the Messenger of Allah (peace and blessings be upon him), while I was riding behind him on his mount. The Messenger of Allah (peace and blessings be upon him) called out loudly two or three times:“O Suhail bin Bayda’!”Sayyiduna Suhail (may Allah be pleased with him) would respond from ahead. Anyway, when the Companions heard the Messenger of Allah (peace and blessings be upon him) calling out in this manner, they thought that he wanted to call all of them, so those in front stopped and those behind caught up with the Messenger of Allah (peace and blessings be upon him), until they all gathered together. Then the Messenger of Allah (peace and blessings be upon him) said:“Whoever bears witness that Allah alone is the true deity, Allah makes the Fire forbidden for him and makes Paradise obligatory for him.”In another narration:“Because of this testimony, Allah makes Paradise obligatory for him and frees him from the Fire.”

It is narrated from Sayyiduna Suhail bin Bayda’ (may Allah be pleased with him), he says: We were on a journey with the Messenger of Allah (peace and blessings be upon him), while I was riding behind him on his mount.

It is narrated from Sayyiduna Abu Musa Ash'ari (may Allah be pleased with him), he says: I came to the Noble Prophet (peace and blessings be upon him), while some people from my tribe were also with me. The Prophet (peace and blessings be upon him) said: "Rejoice yourselves and give glad tidings to those who come after you that whoever sincerely bears witness that Allah alone is the true deity, he will enter Paradise." Hearing this, we left the presence of the Noble Prophet (peace and blessings be upon him) to give people the glad tidings, but when we met Sayyiduna Umar (may Allah be pleased with him) ahead, he sent us back to the Messenger of Allah (peace and blessings be upon him) and advised him that (such things should not be told to the common people, otherwise) they will rely on it (and abandon deeds). Hearing this, the Messenger of Allah (peace and blessings be upon him) remained silent.

Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) says: I was also present with the people at the time of Sayyiduna Mu'adh's (may Allah be pleased with him) death. He said: "Lift the curtain of the canopy, I will narrate to you a hadith I heard from the Messenger of Allah (peace and blessings be upon him). Previously, I refrained from narrating this hadith because I feared you would rely solely on it (and neglect deeds). I heard the Prophet (peace and blessings be upon him) say: 'Whoever testifies with sincerity of heart or (the narrator said) with certainty that there is no deity except Allah, he will not enter the Fire.'" And on another occasion he said: "He will enter Paradise and the Fire will not touch him."

It is narrated from Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said to him: "The keys to Paradise are bearing witness to «لَا إِلَهَ إِلَّا اللَّهُ» ."
