A. There is hadith in sahih al bukhari (vol. 3 book of fasting, hadith 1969) “aisha (r. a) related that the prophet (saw) never fasted a complete month except in Ramadan and he didn’t fast in any month as many days as he fasted in the month of shabaan” thus from this hadith we come to know that prophet (saw ) used to welcome or prepare for the month of Ramadan by fasting many days in the previous month, i.e. the month of shabaan. And further if you read in Tirmidhi (Book of supplications, Hadith 5431) which says that Talha (r.a) says on the authority of his father that whenever the prophet (saw) saw the new moon he always used to pray to Allah (swt) and say “O Allah bless us in this month (and he used to mention the name of the month) keep us stead fast in faith in this month. This is how prophet (saw) used to pray to Allah (swt) whenever he used to see the new moon. It wasn’t specifically only for the new moon of the Ramadan but it was for all the new moons he used to see. He used to mention about coming of this blessed month to the people. Prophet (saw) addressed the people in hadith (Musanad Ahmad, vol 2, page 230, hadith 7148) “O people this blessed month is approaching you and Allah (swt) has ordained on you to fast in this month. Gates of the heaven will be opened in this month and gates of hell will be closed and the devil will be chained, and in this month there is a night which is better than a thousand months and whosoever is deprived of Allah’s (swt) blessing in this month, he is truly the deprived person.
