Verily the people before you went to their doom because they had put too many questions to their Prophets and then disagreed with their teachings.

حَدَّثَنِي حَرْمَلَةُ بْنُ يَحْيَى التُّجِيبِيُّ، أَخْبَرَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي يُونُسُ، عَنِ ابْنِ شِهَابٍ، أَخْبَرَنِي أَبُو سَلَمَةَ بْنُ عَبْدِ الرَّحْمَنِ، وَسَعِيدُ بْنُ الْمُسَيَّبِ، قَالاَ كَانَ أَبُو هُرَيْرَةَ يُحَدِّثُ أَنَّهُ سَمِعَ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " مَا نَهَيْتُكُمْ عَنْهُ فَاجْتَنِبُوهُ وَمَا أَمَرْتُكُمْ بِهِ فَافْعَلُوا مِنْهُ مَا اسْتَطَعْتُمْ فَإِنَّمَا أَهْلَكَ الَّذِينَ مِنْ قَبْلِكُمْ كَثْرَةُ مَسَائِلِهِمْ وَاخْتِلاَفُهُمْ عَلَى أَنْبِيَائِهِمْ " .
