It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "Every inhabitant of Hell will see his place in Paradise and will say: 'Alas! If only Allah had guided me (then that place would have been my abode).' This will become a cause of regret and remorse for him. And every inhabitant of Paradise will see his place in Hell and will say: 'If Allah had not guided me (then that place would have been my abode).' This will become a cause for him to thank Allah Almighty." Then the Messenger of Allah (peace and blessings of Allah be upon him) recited this verse: «أَنْ تَقُولَ نَفْسٌ يَا حَسْرَتَى عَلَى مَا فَرَّطْتُ فِي جَنْبِ اللَّـهِ» (39-az-Zumar:56) "(Lest) a soul should say: 'Alas, my grief that I neglected the duty to Allah and I was indeed among those who mocked.'"

Ali bin Khalid says that Sayyiduna Abu Umamah Bahili (may Allah be pleased with him) passed by Khalid bin Yazid bin Muawiyah. He asked him about the gentlest words he had heard from the Messenger of Allah (peace and blessings be upon him). He said: I heard the Messenger of Allah (peace and blessings be upon him) say: "Every one of you will enter Paradise, except the one who rebelled against Allah in the way a camel bolts away from its owner."

Sayyiduna Abu Sa‘id Khudri (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said:“By Him in Whose hand is my soul! All of you will enter Paradise, except those who refuse and rebel against (the obedience of Allah and His Messenger) like a camel that strays away.”The Companions asked:“O Messenger of Allah, who would refuse to enter Paradise?”He (peace and blessings be upon him) said:“Whoever obeys me will enter Paradise, and whoever disobeys me, he has (in effect) refused (to enter Paradise).”

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "If there are one hundred thousand or more people sitting in this mosque, and among them a single person from Hell breathes, then due to his effect, the mosque along with all the people in it would burn."

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "When a person seeks refuge from the Fire (of Allah) seven times in a day, Hell says: 'O my Lord! Your such-and-such servant is seeking refuge from me, so grant him refuge.' Likewise, when a person asks Allah for Paradise seven times in a day, Paradise says: 'O my Lord! Your such-and-such servant is asking You for me, so admit him into Paradise.'"

Abu Huraira (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Every one of you has two abodes: one abode in Paradise and another in Hell. If he dies and enters Hell, then the people of Paradise inherit his abode. This is the meaning of Allah Almighty's statement: «أُولَـئِكَ هُمُ الْوَارِثُونَ» (23:10 Al-Mu’minun) 'They are the inheritors.'"

It is narrated from Sayyiduna Abu Musa (may Allah be pleased with him) that the Prophet (peace and blessings of Allah be upon him) said: "Whoever fasts for the entire period (of time), Hell will be made so narrow for him." Then he (the Prophet) gestured by tying a knot of ninety (90).

Sayyiduna Hudhayfah bin Yaman (may Allah be pleased with him) says that the Companions of the Messenger said: Sayyiduna Ibrahim (peace be upon him) is the Friend of Allah, Sayyiduna Isa (peace be upon him) is the Word and Spirit of Allah, and Allah spoke directly to Sayyiduna Musa (peace be upon him). O Messenger of Allah! What has been granted to you? He (peace and blessings be upon him) said: "On the Day of Resurrection, all the children of Adam (peace be upon him) will be under my banner. I am the one for whom the gates of Paradise will be opened first."

Sayyiduna Anas (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "A person from among the people of Paradise will be brought, and Allah Almighty will say to him: 'O son of Adam! How did you find your abode?' He will say: 'O my Lord! It is the best abode.' Allah Almighty will say: 'Ask and wish for more.' He will say: 'What should I ask for and what should I wish for? Yes, if You return me to the world (then it is fine) so that I may be martyred ten times in Your path.' He will express this wish because of the virtue and honor of martyrdom. Then a person from among the people of Hell will be brought. Allah Almighty will ask: 'How did you find your abode?' He will say: 'O my Lord! It is the worst abode.' The Lord Almighty will say: 'Will you give the earth full of gold to be freed from it?' He will say: 'Yes, O my Lord!' Allah Almighty will say: 'You are lying, I had asked you for something less and easier than this, but you did not fulfill that either.' Then he will be returned to the Fire."

Sayyiduna Abu Wa’il (may Allah be pleased with him) said that someone said to Sayyiduna Usamah (may Allah be pleased with him):“Will you not go to Sayyiduna Uthman (may Allah be pleased with him) and speak to him about what he has done?”He replied:“Do you think that whatever I speak to him about, I will inform you people of it? I will speak to him privately without opening the door, because in the light of a hadith, I do not wish to be the first to open the door, nor can I say about my leader, if he is truly a leader, that he is the best of people.”It was asked:“Which hadith is that?”He said that the Messenger of Allah (peace and blessings be upon him) said:“A man will be brought on the Day of Resurrection and thrown into the Fire. His intestines will come out and he will circle around them like a donkey circles around a millstone. The people will see him and say: ‘O so-and-so! Why were you thrown in here? You used to command us to do good and forbid us from evil!’ He will say: ‘I used to command you to do good, but I did not do it myself, and I used to forbid you from evil, but I did not refrain from it myself.’”
