AsSalaamu 'alaikum,waRahmatullahi,waBarakaatuhu, My respected brothers and sisters in Islam, my inquiry is clarity on how we, are to increase in fasting during the Month of Sha'baan, many fast during the regular weeks and months that fasting is not obligatory by observing fasts on Mondays, Thursdays, and the White days, the 13th,14th, and 15th of each month of the lunar calendar. Please advise us from the authentic prrofs,insha'Allah!
