(as regards the Verse):--'You shall surely travel from stage to stage (in this life and in the Hereafter).' (It means) from one state to another. That concerns your Prophet.
Sahih al-Bukhari Book 65, Hadith 461
← Previous Hadith Allah's Messenger (ﷺ) said," (On the Day of Resurrection) any one whose account will be taken will be ruined (i.e. go to Hell)." I said, "O Allah's Messenger (ﷺ)! May Allah make me be sacrificed for you. Doesn't Allah say: "Then as for him who will be given his record in his right hand, he surely will receive an easy reckoning.?" (84.7-8) He replied, "That is only the presentation of the accounts; but he whose record is questioned, will be ruined."

(This hadith is also narrated through two other chains)

Sahih al-Bukhari Book 65, Hadith 460 Next Hadith → The first of the companions of the Prophet (ﷺ) who came to us (in Medina), were Mus`ab bin `Umar and Ibn Um Maktum, and they started teaching us the Qur'an. Then came `Ammar, Bilal and Sa`d. Afterwards `Umar bin Al-Kkattab came along with a batch of twenty (men): and after that the Prophet (ﷺ) came. I never saw the people of Medina so pleased with anything as they were with his arrival, so that even the little boys and girls were saying, "This is Allah's Messenger (ﷺ) who has come." He (the Prophet (ﷺ) ) did not come (to Medina) till I had learnt Surat Al-Ala and also other similar Suras.
