The lote tree of Paradise is thornless, and in place of every thorn a fruit is set

It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him) that the Companions of the Messenger of Allah (peace and blessings be upon him) used to say: Allah benefits us through the Bedouins and their questions. One day a Bedouin came and said: O Messenger of Allah, Allah has mentioned in the Qur'an a harmful tree, and I did not think that there would be a tree in Paradise that would harm its owner. The Messenger of Allah (peace and blessings be upon him) said: "Which tree is that?" He said: The lote tree, because it has thorns. So the Messenger of Allah (peace and blessings be upon him) said: "(Allah has said:) 'Among thornless lote trees' [Surah al-Waqi'ah: 28]. Allah will remove its thorns and put fruit in place of its thorns. It will be such a lote tree that a single fruit of it will split into seventy-two (72) kinds of food, no colour of which will resemble another."
This hadith has a sahih (authentic) chain of narration, but the two Shaykhs did not record it.

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) concerning the saying of Allah, the Mighty and Majestic: "And in the shade of black smoke" [Surah al-Waqi'ah: 43], that he said: "(It means) black-coloured smoke."
This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.
