that the Messenger of Allah (ﷺ) said: "Whoever spends a pair of things in the path of Allah, he will be called in Paradise: 'O Worshiper of Allah, this is good.' And whoever is among the people of Salat, he will be called from the gate of Salat, and whoever was among from the people of Jihad, he will be called from the gate of Jihad. And whoever was among the people of charity, then he will be called from the gate of charity, and whoever was from the people of fasting, then he will be called from the gate of Ar-Rayyan." So Abu Bakr said: "May my father and mother be ransomed for you! The one who is called from these gates will be free of all worries. But will anyone be called from all of those gates?" He (ﷺ) said: "Yes, and I hope that you are among them."
Jami` at-Tirmidhi Book 49, Hadith 70
"I had no confusion in my mind from that time I embraced Islam, except when I recited a verse and another man recited it differently. I said: 'The Messenger of Allah (ﷺ) taught me this.' And the other man said: 'The Messenger of Allah (ﷺ) taught me too.' So I went to the Prophet (ﷺ) and said: 'O Prophet of Allah, did you not teach me such and such a verse?' He said: 'Yes.' The other man said: 'Did you not teach me such and such a verse?' He said: 'Yes. Jibril and Mika'il, peace be upon them, came to me, and Jibril sat on my right and Mika'il on my left. Jibril, peace be upon him, said: "Recite the Quran with one way of recitation.' Mika'il said: 'Teach him more, teach him more- until there were seven modes of recitation, each of which is good and sound.'"
Sunan an-Nasa'i Book 11, Hadith 66
Allah's Messenger (ﷺ) was informed that I have said: "By Allah, I will fast all the days and pray all the nights
as long as I live." On that, Allah's Messenger (ﷺ) asked me. "Are you the one who says: 'I will fast all the
days and pray all the nights as long as I live?' " I said, "Yes, I have said it." He said, "You cannot do
that. So fast (sometimes) and do not fast (sometimes). Pray and sleep. Fast for three days a month, for
the reward of a good deed is multiplied by ten time, and so the fasting of three days a month equals
the fasting of a year." I said, "O Allah's Messenger (ﷺ)! I can do (fast) more than this." He said, "Fast on
every third day. I said: I can do (fast) more than that, He said: "Fast on alternate days and this was the
fasting of David which is the most moderate sort of fasting." I said, "O Allah's Messenger (ﷺ)! I can do (fast)
more than that." He said, "There is nothing better than that."
Sahih al-Bukhari Book 60, Hadith 90
Allah's Messenger (ﷺ) said, "Noah will be called on the Day of Resurrection and he will say, 'Labbaik and
Sa`daik, O my Lord!' Allah will say, 'Did you convey the Message?' Noah will say, 'Yes.' His nation
will then be asked, 'Did he convey the Message to you?' They will say, 'No Warner came to us.' Then
Allah will say (to Noah), 'Who will bear witness in your favor?' He will say, 'Muhammad and his
followers. So they (i.e. Muslims) will testify that he conveyed the Message. And the Apostle
(Muhammad) will be a witness over yourselves, and that is what is meant by the Statement of Allah
"Thus We have made of you a just and the best nation that you may be witnesses over mankind and
the Apostle (Muhammad) will be a witness over yourselves."
