[Machine] The Messenger of Allah ﷺ prohibited hastening the month of Ramadan by fasting a day or two, except for a man who used to fast regularly and then would observe this fast.  

نَهَى رَسُولُ اللهِ ﷺ عَنْ أَنْ يُعَجَّلَ شَهْرُ رَمَضَانَ بِصَوْمِ يَوْمٍ أَوْ يَوْمَيْنِ إِلَّا رَجُلًا كَانَ يَصُومُ صِيَامًا فَيَأْتِي ذَلِكَ عَلَى صِيَامِهِ  

[Machine] He did not fast for a month from the year except for Sha'ban, as he used to fast the entire month of Sha'ban.  

كَانَ لَا يَصُومُ مِنَ السَّنَةِ شَهْرًا إِلَّا شَعْبَانَ فَإِنَّهُ كَانَ يَصُومُ شَعْبَانَ كُلَّهُ  

[Machine] The Prophet ﷺ did not fast for two consecutive months except for the months of Sha'ban and Ramadan. This is mentioned in the narration of Shu'bah and in the narration of Sufyan it is mentioned that she said, "I have never seen the Messenger of Allah ﷺ fasting for two consecutive months except that he would connect Sha'ban with Ramadan."  

النَّبِيَّ ﷺ لَمْ يَكُنْ يَصُومُ شَهْرَيْنِ يَجْمَعُ بَيْنَهُمَا إِلَّا شَعْبَانَ وَرَمَضَانَ لَفْظُ حَدِيثِ شُعْبَةَ وَفِي رِوَايَةِ سُفْيَانَ قَالَتْ مَا رَأَيْتُ رَسُولَ اللهِ ﷺ صَائِمًا شَهْرَيْنِ مُتَتَابِعَيْنِ إِلَّا أَنَّهُ كَانَ يَصِلُ شَعْبَانَ بِرَمَضَانَ  

She never saw the Prophet ﷺ fasting the whole month except Sha'ban which he combined with Ramadan. (Using translation from Abū Dāʾūd 2336)   

النَّبِيِّ ﷺ أَنَّهُ لَمْ يَكُنْ يَصُومُ مِنَ السَّنَةِ شَهْرًا تَامًّا إِلَّا شَعْبَانَ يَصِلُهُ بِرَمَضَانَ
