It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Noble Prophet, peace and blessings be upon him, instructed Sayyiduna Bilal, may Allah be pleased with him, to announce among the people that only and only a Muslim soul will enter Paradise.

Abu Zubair (may Allah have mercy on him) says: I asked Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) about the one who was killed, regarding whom Sayyiduna Suhaim (may Allah be pleased with him) had made an announcement. He said: We were at Hunain when the Noble Prophet (peace and blessings be upon him) ordered Sayyiduna Suhaim (may Allah be pleased with him) to announce among the people that only and only a believer will enter Paradise.

Abu Zubair (may Allah have mercy on him) says: I asked Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) about that murdered person regarding whom Sayyiduna Suhaim (may Allah be pleased with him) had made an announcement. He said: We were at Hunain when the Noble Prophet (peace and blessings be upon him) ordered Sayyiduna Suhaim (may Allah be pleased with him) to announce among the people that only and only a believer will enter Paradise.

It is narrated from Sayyiduna Mahmood bin Labeed (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: "Indeed, Allah Almighty protects His believing servant from the world (and its wealth and possessions), even though He loves him. Its example is just like you fear for your sick person and keep him away from food and drink."

It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "There are three types of believers in the world: (1) Those who believed in Allah and His Messenger and then did not fall into any doubt, and strove in the way of Allah with their wealth and their lives; (2) The person about whom other people feel secure regarding their wealth and lives; and (3) The person who looks towards greed but abandons it for the sake of Allah Almighty."

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "A believer is simple-hearted and noble, while a wicked person is deceitful, treacherous, and vile (and despicable)."

It is also narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Noble Prophet, peace and blessings be upon him, said: "Allah Almighty says: In My sight, the believer is at the station of every kind of goodness and virtue. I am drawing out his soul from his sides, and even at that time he is praising Me."

In another narration reported from Sayyiduna Abu Hurairah, may Allah be pleased with him, the Noble Prophet, peace and blessings be upon him, said: "Indeed, the believer wearies his devils just as one of you wearies his camel during a journey."

Sayyiduna Fadala bin Ubaid (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) said during the Farewell Pilgrimage:“Shall I not tell you about the believer? The believer is the one from whom people are safe regarding their wealth and lives. The Muslim is the one from whose tongue and hand other Muslims are safe. The Mujahid is the one who strives against his own self in obedience to Allah Almighty, and the Muhajir is the one who abandons mistakes and sins.”

It is narrated from Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Do you know who is a Muslim?" They said: "Allah and His Messenger know best." The Prophet (peace and blessings be upon him) said: "A Muslim is the one from whose tongue and hand other Muslims are safe." The Prophet (peace and blessings be upon him) said: "Do you know who is a believer?" They said: "Allah and His Messenger know best." The Prophet (peace and blessings be upon him) said: "A believer is the one from whom other believers are safe regarding their lives and wealth, and a migrant is the one who abandons evil and refrains from it."
