[Machine] In his statement "Verily, negligence is an increase in disbelief" [Surah At-Tawbah: 37], he (Abdullah ibn Mas'ud) said they performed Hajj in the month of Dhul-Hijjah for two consecutive years, then they performed Hajj in the month of Muharram for two consecutive years. So they used to perform Hajj every year, every month for two consecutive years, until the Hajj of Abu Bakr coincided with the end of the two years in the month of Dhul-Qa'dah before the Hajj of the Prophet ﷺ by one year. Then the Prophet ﷺ performed Hajj the following year in Dhul-Hijjah. This is the time when the Messenger of Allah ﷺ said in his sermon: "Verily, time has turned as it was on the day He created the heavens and the earth."  

فِي قَوْلِهِ {إِنَّمَا النَّسِيءُ زِيَادَةٌ فِي الْكُفْرِ} [التوبة 37] قَالَ حَجُّوا فِي ذِي الْحِجَّةِ عَامَيْنِ ثُمَّ حَجُّوا فِي الْمُحَرَّمِ عَامَيْنِ فَكَانُوا يَحُجُّونَ فِي كُلِّ سَنَةٍ فِي كُلِّ شَهْرٍ عَامَيْنِ حَتَّى وَافَقَتْ حَجَّةُ أَبِي بَكْرٍ ؓ الْآخِرَ مِنَ الْعَامَيْنِ فِي ذِي الْقَعْدَةِ قَبْلَ حَجَّةِ النَّبِيِّ ﷺ بِسَنَةٍ ثُمَّ حَجَّ النَّبِيُّ ﷺ مِنْ قَابِلٍ فِي ذِي الْحِجَّةِ فَذَلِكَ حِينَ يَقُولُ رَسُولُ اللهِ ﷺ فِي خُطْبَتِهِ إِنَّ الزَّمَانَ قَدِ اسْتَدَارَ كَهَيْئَتِهِ يَوْمَ خَلَقَ السَّمَاوَاتِ وَالْأَرْضَ
