"The Messenger of Allah (s.a.w) was asked about Waraqah. Khadijah said to him: 'He believed in you, but he died before your advent.' So the Messenger of Allah (s.a.w) said: 'I saw him in a dream, and upon him were white garments. If he were among the inhabitants of the Fire then he would have been wearing other than that.'"
Jami` at-Tirmidhi Book 34, Hadith 19
← Previous Hadith "One day the Prophet (s.a.w) said: "'Who among you had a dream?' A man said: "I did. I saw as if a scale had descended from the Heavens in which you and Abu Bakr were weighed So you outweighed Abu Bakr. Abu Bkar and 'Umar were weighed, and Abu Bakr outweighed ('Umar). 'Umar and 'Uthman were weighed and 'Umar outweighed ('Uthman). Then the scale was raised up.' Then I saw dislike in the the face of Messenger of Allah (s.a.w)."

Jami` at-Tirmidhi Book 34, Hadith 18 Next Hadith → "I saw that the people had gathered, so Abu Bakr drew a bucket or two buckets- in him was some weakness- and Allah forgive him. Then 'Umar stood to draw and the bucket turned into a very large one, and I have never seen a strong man toiling so hard until it was as if the people had gathered at a (camel) watering hole."
