Allah's Messenger (ﷺ) in his fatal illness came out, wrapped with a sheet, and his head was wrapped with an
oiled bandage. He sat on the pulpit, and praising and glorifying Allah, he said, "Now then, people will
increase but the Ansar will decrease in number, so much so that they, compared with the people, will
be just like the salt in the meals. So, if any of you should take over the authority by which he can
either benefit some people or harm some others, he should accept the goodness of their good people
(i.e. Ansar) and excuse the faults of their wrong-doers." That was the last gathering which the Prophet (ﷺ)
attended.
Sahih al-Bukhari Book 61, Hadith 132
from Ibn 'Abbas, regarding the saying of Allah, Most High: Alif Lam Mim. The Romans have been defeated. In the nearest land (30:1-3)" he said: "Ghulibat wa Ghalabat (defeated and then victorious)." He said: "The idolaters wanted the Persians to be victorious over the Romans because they too were people who worshiped idols, while the Muslims wanted the Romans to be victorious over the Persians because they were people of the Book. This was mentioned to Abu Bakr, so Abu Bakr mentioned that to the Messenger of Allah (ﷺ) and he said: 'They will certainly prevail.' Abu Bakr mentioned that to them, and they said: 'Make a wager between us and you; if we win, we shall get this and that, and if you win, you shall get this or that.' He made the term five years, but they (the Romans) were not victorious. They mentioned that to the Prophet (ﷺ) and he said: "Why did you not make it less (than)" - He (one of the narrators said): I think he said: "ten?" He said: Sa'eed said: "Al-Bid' is what is less than then" - he said: "Afterwards the Romans have been victorious." He said: "That is what Allah Most High said: 'Alif Lam Mim. The Romans have been defeated' up to His saying: 'And on the day, the believers will rejoice - with the help of Allah. He helps whom He wills (30:1-5).' Sufyan said: "I heard that they were victorious over them on the Day of Badr."
Jami` at-Tirmidhi Book 47, Hadith 245
"We said: 'O Messenger of Allah! What is wrong with us that when we are with you our hearts are softened and we feel free of desire for this world, and we are of the people of the Hereafter. But when we depart from you and socialize with our families and our children, we do not recognize ourselves(i.e., we are changed persons)?' So the Messenger of Allah (s.a.w) said: 'If you were to be in that condition when you depart from me, the angels would have surely visited you in your houses. And if you did not sin, Allah would surely have brought anew creation that they may sin, so that then He may forgive them.'"He said: "I said: 'O Messenger of Allah! From what was the creation created?' He said: 'From water.' We said: 'Paradise, what is it constructed of?' He said,'Bricks of silver and bricks of gold. Its mortar is musk of a strong fragrance, and its pebbles are pearls and rubies, and its earth is saffron. Whoever enters it shall live and shall not suffer, and shall feel joy and shall not die, nor shall their clothes wear out, nor shall their youth come to an end.' Then he said: 'Three persons , their supplication is not rejected: The just ruler, the fasting person when he breaks his fast, and the supplication of the wronged person. It is raised up above the clouds, and the gates of Heaven are opened up for it, and the Lord, Blessed and Exalted says: I shall surely come to your aid, even if after a time.'"
Jami` at-Tirmidhi Book 38, Hadith 4
"Jibril, peace be upon him, came to the Prophet (ﷺ) when the sun had passed its zenith and said: 'Get up, O Muhammad, and pray Zuhr when the sun has passed its zenith.' Then he waited until a man's shadow was equal to his height. Then he came to him for 'Asr and said: 'Get up, O Muhammad, and pray 'Asr.' Then he waited until the sunset, then he came to him and said: 'Get up, O Muhammad, and pray Maghrib.' So he got up and prayed it when the sun had set. Then he waited until the twilight disappeared, then he came to him and said: 'Get up, O Muhammad, and pray 'Isha'.' So he got up and prayed it. Then he came to him when dawn broke and said: 'Get up, O Muhammad, and pray.' So he got up and prayed Subh.' So he got up and prayed Subh. Then he came to him the next day when a man's shadow was equal to his height, and said: 'Get up, O Muhammad, and pray.' So he prayed Zuhr. Then Jibril came to him when a man's shadow was equal to twice his length and said: 'Get up, O Muhammad, and pray.' So he prayed 'Asr. Then he came to him for Maghrib when the sun set, at exactly the same time as the day before, and said: 'Get up, O Muhammad, and pray.' So he prayed Maghrib. Then he came to him for 'Isha' when the first third of the night had passed, and said: 'Get up and pray.' So he prayed 'Isha'. Then he came to him for Subh when it had become very bright, and said: 'Get up and pray.' So he prayed Subh. Then he said: 'The times of prayer one between those two (limits).'"
