the Prophet commanded them to fast the three days of Al-Bid. He said: "That is (equivalent to) fasting for the whole month." (Using translation from Nasāʾī 2431)
أَنَّ النَّبِيَّ ﷺ أَمَرَهُمْ بِصِيَامِ ثَلَاثَةِ أَيَّامٍ الْبِيضِ وَقَالَ «هُنَّ صَوْمُ الشَّهْرِ»
the Messenger of Allah used to enjoin (fasting) these days of Al-Bid and he said: "That is (equivalent to) fasting for the whole month."
أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يَأْمُرُ بِهَذِهِ الأَيَّامِ الثَّلاَثِ الْبِيضِ وَيَقُولُ هُنَّ صِيَامُ الشَّهْرِ

[Machine] The translation of the passage into English is:
"The Messenger of Allah, ﷺ , used to command them to fast the white days and he would say, 'They are the fasting of the month,' or he said, 'of the lifetime.'"
أَنَّ رَسُولَ اللهِ ﷺ كَانَ يَأْمُرُهُمْ بِصِيَامِ أَيَّامِ الْبِيضِ وَيَقُولُ هُنَّ صِيَامُ الشَّهْرِ أَوْ قَالَ الدَّهْرِ
