Can someone highlight and explain in detail the various fasts that are recommended during the month of Shaban based on the authentic hadeeth?
The rule is to fast the first half of Sha'ban, and among the wisdom in this is getting used to fasting so when Ramadan comes it is a bit easier, so when the half of Sha'ban comes then we shouldn't fast.
إِذَا انْتَصَفَ شَعْبَانُ فَلاَ تَصُومُوا
When the middle of Sha'ban comes, do not fast
I am unsure whether this is what you where referring to by "various fasts".
