حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا عَبْدُ الْوَهَّابِ، حَدَّثَنَا أَيُّوبُ، عَنْ مُحَمَّدِ بْنِ سِيرِينَ، عَنِ ابْنِ أَبِي بَكْرَةَ، عَنْ أَبِي بَكْرَةَ ـ رضى الله عنه ـ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " الزَّمَانُ قَدِ اسْتَدَارَ كَهَيْئَتِهِ يَوْمَ خَلَقَ السَّمَوَاتِ وَالأَرْضَ، السَّنَةُ اثْنَا عَشَرَ شَهْرًا، مِنْهَا أَرْبَعَةٌ حُرُمٌ، ثَلاَثَةٌ مُتَوَالِيَاتٌ ذُو الْقَعْدَةِ وَذُو الْحِجَّةِ وَالْمُحَرَّمُ، وَرَجَبُ مُضَرَ الَّذِي بَيْنَ جُمَادَى وَشَعْبَانَ ".

Narrated Abu Bakra: The Prophet said. "(The division of time has turned to its original form which was current when Allah created the Heavens and the Earths. The year is of twelve months, out of which four months are sacred: Three are in succession Dhul-Qa' da, Dhul-Hijja and Muharram, and (the fourth is) Rajab of (the tribe of) Mudar which comes between Jumadiath-Thaniyah and Sha ban."
