مَا كَانَ لِبَشَرٍ أَن يُؤْتِيَهُ ٱللَّهُ ٱلْكِتَٰبَ وَٱلْحُكْمَ وَٱلنُّبُوَّةَ ثُمَّ يَقُولَ لِلنَّاسِ كُونُوا۟ عِبَادًۭا لِّى مِن دُونِ ٱللَّهِ وَلَٰكِن كُونُوا۟ رَبَّٰنِيِّۦنَ بِمَا كُنتُمْ تُعَلِّمُونَ ٱلْكِتَٰبَ وَبِمَا كُنتُمْ تَدْرُسُونَ
It is not (possible) for any human being unto whom Allah had given the Scripture and wisdom and the prophethood that he should afterwards have said unto mankind: Be slaves of me instead of Allah; but (what he said was): Be ye faithful servants of the Lord by virtue of your constant teaching of the Scripture and of your constant study thereof.
Surah Aal-i-Imraan(3:79)
Sahih al-Bukhari
The Two Festivals (Eids)
Chapter: If the Imam is asked about something while he is delivering the Khutba
Narrated Anas bin Malik:
Allah's Messenger (ﷺ) offered the prayer on the day of Nahr and then delivered the Khutba and ordered that whoever had slaughtered his sacrifice before the prayer should repeat it, that is, should slaughter another sacrifice. Then a person from the Ansar stood up and said, "O Allah's Messenger (ﷺ)! because of my neighbors (he described them as being very needy or poor) I slaughtered before the prayer. I have a young she-goat which, in my opinion, is better than two sheep." The Prophet (ﷺ) gave him the permission for slaughtering it as a sacrifice.
