The Prophet ﷺ said: There are three types of people whose prayer is not accepted by Allah: One who goes in front of people when they do not like him; a man who comes dibaran, which means that he comes to it too late; and a man who takes into slavery an emancipated male or female slave.
أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يَقُولُ ثَلاَثَةٌ لاَ يَقْبَلُ اللَّهُ مِنْهُمْ صَلاَةً مَنْ تَقَدَّمَ قَوْمًا وَهُمْ لَهُ كَارِهُونَ وَرَجُلٌ أَتَى الصَّلاَةَ دِبَارًا وَالدِّبَارُ أَنْ يَأْتِيَهَا بَعْدَ أَنْ تَفُوتَهُ وَرَجُلٌ اعْتَبَدَ مُحَرَّرَهُ
