Narrated Alqama:
I asked 'Aisha "Did Allah s Apostle, use to choose some special days (for fasting)?" She replied, "No, but he used to be regular (constant) (in his service of worshipping). Who amongst you can endure what Allah's Apostle used to endure?"
حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى، عَنْ سُفْيَانَ، عَنْ مَنْصُورٍ، عَنْ إِبْرَاهِيمَ، عَنْ عَلْقَمَةَ، قُلْتُ لِعَائِشَةَ ـ رضى الله عنها ـ هَلْ كَانَ رَسُولُ اللَّهِ ﷺ يَخْتَصُّ مِنَ الأَيَّامِ شَيْئًا قَالَتْ لاَ، كَانَ عَمَلُهُ دِيمَةً، وَأَيُّكُمْ يُطِيقُ مَا كَانَ رَسُولُ اللَّهِ ﷺ يُطِيقُ
