I heard `Imran bin Husain saying, "The Prophet (ﷺ) said, 'The best people are those living in my generation, then those coming after them, and then those coming after (the second generation)." `Imran said "I do not know whether the Prophet (ﷺ) mentioned two or three generations after your present generation. The Prophet (ﷺ) added, 'There will be some people after you, who will be dishonest and will not be trustworthy and will give witness (evidences) without being asked to give witness, and will vow but will not fulfill their vows, and obesity will appear among them."
Sahih al-Bukhari Book 52, Hadith 15
← Previous Hadith My mother asked my father to present me a gift from his property; and he gave it to me after some hesitation. My mother said that she would not be satisfied unless the Prophet (ﷺ) was made a witness to it. I being a young boy, my father held me by the hand and took me to the Prophet (ﷺ) . He said to the Prophet, "His mother, bint Rawaha, requested me to give this boy a gift." The Prophet (ﷺ) said, "Do you have other sons besides him?" He said, "Yes." The Prophet (ﷺ) said, "Do not make me a witness for injustice." Narrated Ash-Shu`bi that the Prophet (ﷺ) said, "I will not become a witness for injustice."

Sahih al-Bukhari Book 52, Hadith 14 Next Hadith → The Prophet (ﷺ) said, "The people of my generation are the best, then those who follow them, and then whose who follow the latter. After that there will come some people whose witness will go ahead of their oaths, and their oaths will go ahead of their witness." Ibrahim (a sub-narrator) said, "We used to be beaten for taking oaths by saying, 'I bear witness by the Name of Allah or by the Covenant of Allah."
