إِنَّ ٱلَّذِينَ كَفَرُوا۟ لَوْ أَنَّ لَهُم مَّا فِى ٱلْأَرْضِ جَمِيعًۭا وَمِثْلَهُۥ مَعَهُۥ لِيَفْتَدُوا۟ بِهِۦ مِنْ عَذَابِ يَوْمِ ٱلْقِيَٰمَةِ مَا تُقُبِّلَ مِنْهُمْ ۖ وَلَهُمْ عَذَابٌ أَلِيمٌۭ
As for those who disbelieve, lo! if all that is in the earth were theirs, and as much again therewith, to ransom them from the doom on the Day of Resurrection, it would not be accepted from them. Theirs will be a painful doom.
Surah Al-Maaida(5:36)
Sahih al-Bukhari
Prophetic Commentary on the Qur'an (Tafseer of the Prophet (pbuh))
"O Prophet! Why do you forbid (for yourself) that which Allah has allowed to you?..." (V.66:1)
Narrated `Aisha:
Allah's Messenger (ﷺ) used to drink honey in the house of Zainab, the daughter of Jahsh, and would stay there with her. So Hafsa and I agreed secretly that, if he come to either of us, she would say to him. "It seems you have eaten Maghafir (a kind of bad-smelling resin), for I smell in you the smell of Maghafir," (We did so) and he replied. "No, but I was drinking honey in the house of Zainab, the daughter of Jahsh, and I shall never take it again. I have taken an oath as to that, and you should not tell anybody about it."
