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» ."

It is narrated from Sayyiduna Rifa’ah Juhani (may Allah be pleased with him), he says: We were on a journey with the Messenger of Allah (peace and blessings be upon him) from Makkah to Madinah. When we reached the place of Kadid or Qudayd, people began to ask permission to return to their homes, and the Messenger of Allah (peace and blessings be upon him) kept granting them permission. Then the Messenger of Allah (peace and blessings be upon him) stood up, praised and glorified Allah, and said:“What will be the state of those people regarding the side of the tree to which the Messenger of Allah (peace and blessings be upon him)...”When we heard these words, all the people began to weep. A man (i.e., Sayyiduna Abu Bakr, may Allah be pleased with him) said:“After this, whoever seeks permission from you will be foolish.”Then the Messenger of Allah (peace and blessings be upon him) praised Allah and said:“Whoever bears witness with a sincere heart that Allah alone is the true deity and I am the Messenger of Allah, and then remains steadfast on the right path, I bear witness before Allah regarding him that he will go to Paradise.”Then the Messenger of Allah (peace and blessings be upon him) said:“My Lord has promised me that He will admit seventy thousand people from my Ummah into Paradise without any reckoning or punishment, and I hope that they will not enter it until you and your righteous forefathers, wives, and children have built your homes in Paradise.”

(Second Chain) It is narrated from Sayyiduna Rifa’ah Juhani, may Allah be pleased with him, who says: We were returning from Makkah Mukarramah with the Messenger of Allah, peace and blessings be upon him, when people began to seek permission (to leave). Then the Prophet, peace and blessings be upon him, praised Allah Almighty and spoke words of goodness, and then said:“I bear witness before Allah Almighty that whoever believes in Allah and the Last Day and then continues upon the path of righteousness, he will proceed towards Paradise.”Whenever the Prophet, peace and blessings be upon him, would take an oath, he would say:“By Him in Whose hand is the soul of Muhammad.”

(The third chain) It is narrated from Sayyiduna Rifa’ah Juhani, may Allah be pleased with him, he says: We were on a journey with the Messenger of Allah, peace and blessings be upon him, when we were at the place of Kudaid or ‘Arafah. Then the Prophet, peace and blessings be upon him, praised Allah Almighty and spoke words of goodness, and then said:“I bear witness before Allah Almighty that whoever believes in Allah and the Last Day and then continues upon the path of righteousness, he will proceed towards Paradise.”

It is narrated from Sayyiduna Uthman bin Affan, may Allah be pleased with him, that the Noble Prophet, peace and blessings be upon him, said: "Whoever dies knowing that Allah Almighty alone is the true deity, he will enter Paradise."

It is also narrated from Sayyiduna Uthman bin Affan, may Allah be pleased with him, who says: I heard the Messenger of Allah, peace and blessings be upon him, say: "I know a word that whoever says it with sincerity of heart, the Fire will be made forbidden for him." Upon hearing this, Sayyiduna Umar, may Allah be pleased with him, said: "I will tell you what that word is; it is the word of sincerity by which Allah Almighty honored Muhammad, peace and blessings be upon him, and his companions. It is the word of piety which the Prophet of Allah, peace and blessings be upon him, presented to his uncle Abu Talib at the time of his death, and it is to bear witness to «لَا إِلَهَ إِلَّا اللَّهُ» ."

It is narrated from Sayyiduna Abu Dharr (may Allah be pleased with him), he says: I came to the Messenger of Allah (peace and blessings be upon him), but he was sleeping, wrapped in a white cloth. Then I came again to speak with the Messenger of Allah (peace and blessings be upon him), but he was still resting. After that, when I came, the Messenger of Allah (peace and blessings be upon him) had woken up, so I came and sat near him. The Messenger of Allah (peace and blessings be upon him) said:“Whoever says «لَا إِلَهَ إِلَّا اللَّهُ» and then dies upon it, he will enter Paradise.”I said:“Even if he has committed adultery and theft?”The Messenger of Allah (peace and blessings be upon him) said:“Even if he has committed adultery and theft.”I asked again:“Even if he has committed adultery and theft?”The Messenger of Allah (peace and blessings be upon him) said:“Even if he has committed adultery and theft.”This happened three times, and the fourth time the Messenger of Allah (peace and blessings be upon him) said:“Even if Abu Dharr’s nose becomes dust-covered.”Hearing this, Sayyiduna Abu Dharr (may Allah be pleased with him) left, dragging his lower garment and saying:“Even if Abu Dharr’s nose becomes dust-covered.”

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him), he says: I asked the Messenger of Allah (peace and blessings be upon him): "What treatment has your Lord accorded you regarding intercession?" The Prophet (peace and blessings be upon him) said: "By Him in Whose hand is the life of Muhammad! I thought that the first person to ask me about this from my Ummah would be you, because you possess eagerness for knowledge. By Him in Whose hand is the life of Muhammad! The concern I have about the crowd of my Ummah at the gates of Paradise is, to me, more important than the fulfillment of my intercession, and my intercession is for every person who bears witness to «لَا إِلَهَ إِلَّا اللَّهُ» with sincerity, such that his heart confirms what his tongue says, and his tongue confirms what his heart says."
