وَحَدَّثَنَاهُ حَامِدُ بْنُ عُمَرَ حَدَّثَنَا عَبْدُ الْوَاحِدِ حَدَّثَنَا عَاصِمٌ قَالَ قُلْتُ لأَنَسِ بْنِ مَالِكٍ أَحَرَّمَ رَسُولُ اللَّهِ -صلى الله عليه وسلم- الْمَدِينَةَ قَالَ نَعَمْ مَا بَيْنَ كَذَا إِلَى كَذَا فَمَنْ أَحْدَثَ فِيهَا حَدَثًا - قَالَ - ثُمَّ قَالَ لِى هَذِهِ شَدِيدَةٌ « مَنْ أَحْدَثَ فِيهَا حَدَثًا فَعَلَيْهِ لَعْنَةُ اللَّهِ وَالْمَلاَئِكَةِ وَالنَّاسِ أَجْمَعِينَ لاَ يَقْبَلُ اللَّهُ مِنْهُ يَوْمَ الْقِيَامَةِ صَرْفًا وَلاَ عَدْلاً ». قَالَ فَقَالَ ابْنُ أَنَسٍ أَوْ آوَى مُحْدِثًا.

Asim said: “I said to Anas Bin Malik: ‘Did The Messenger Of Allah (SAW) declare Al-Madinah sacred.’ He said: ‘Yes, what is between such-and-such, and such-and-such .And whoever introduces any Hadath in it’ He said: “Then he said to me: ’this is a serious matter:” Whoever introduces any Hadath in it, upon him be the curse of Allah, the Angles and all the people, and on the day of Resurrection Allah will not accept from him any Sarf nor Adl. “” Ibn Anas said: “Or(anyone) who grants refuge to a Muhdith.”
