Hadith 504190
Chapter 9: Shortening the Prayer - كتاب قصر الصلاة فى السفر
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ زَيْدِ بْنِ أَسْلَمَ، عَنْ عَطَاءِ بْنِ يَسَارٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " اللَّهُمَّ لاَ تَجْعَلْ قَبْرِي وَثَنًا يُعْبَدُ اشْتَدَّ غَضَبُ اللَّهِ عَلَى قَوْمٍ اتَّخَذُوا قُبُورَ أَنْبِيَائِهِمْ مَسَاجِدَ " .
Yahya related to me from Malik from Zayd ibn Aslam from Ata ibn Yasar that the Messenger of Allah, may Allah bless him and grant him peace, said, "O Allah! Do not make my grave an idol that is worshipped. The anger on those who took the graves of their Prophets as places of prostration was terrible."
