وَيَوْمَ يَحْشُرُهُمْ وَمَا يَعْبُدُونَ مِن دُونِ ٱللَّهِ فَيَقُولُ ءَأَنتُمْ أَضْلَلْتُمْ عِبَادِى هَٰٓؤُلَآءِ أَمْ هُمْ ضَلُّوا۟ ٱلسَّبِيلَ
And on the day when He will assemble them and that which they worship instead of Allah and will say: Was it ye who misled these my slaves or did they (themselves) wander from the way?
Surah Al-Furqaan(25:17)
Sahih al-Bukhari
Accepting Information Given by a Truthful Person
Chapter: Acceptance of the information given by one truthful person in about all matters
Narrated Abu Huraira:
Allah's Messenger (ﷺ) finished his prayer after offerings two rak`at only. Dhul-Yaddain asked him whether the prayer had been reduced, or you had forgotten?" The Prophet (ﷺ) said, "Is Dhul-Yaddain speaking the truth?" The people said, "Yes." Then Allah's Messenger (ﷺ) stood up and performed another two rak`at and then finished prayer with Taslim, and then said the Takbir and performed a prostration similar to or longer than his ordinary prostrations; then he raised his head, said Takbir and prostrated and then raised his head (Sahu prostrations).
