Allah's Messenger (ﷺ) said, "When a Muslim is questioned in his grave, he will testify that none has the right to be worshipped but Allah and that Muhammad is Allah's Messenger (ﷺ), and that is what is meant by Allah's Statement:-- "Allah will keep firm those who believe with a Word that stands firm in this world and in the Hereafter." (14.27)
Sahih al-Bukhari Book 65, Hadith 221
← Previous Hadith While we were with Allah's Messenger (ﷺ) he said, "Tell me of a tree which resembles a Muslim man. Its leaves do not fall and it does not, and does not, and does not, and it gives its fruits every now and then." It came to my mind that such a tree must be the date palm, but seeing Abu Bakr and `Umar saying nothing, I disliked to speak. So when they did not say anything, Allah's Messenger (ﷺ) said, "It is the date-palm tree." When we got up (from that place), I said to `Umar, "O my father! By Allah, it came to my mind that it must be the date palm tree." `Umar said, "What prevented you from speaking" I replied, "I did not see you speaking, so I misliked to speak or say anything." `Umar then said, "If you had said it, it would have been dearer to me than so-and-so."
