أحسن الله إليكم I remember on a zoom class I told you I had memorised more than 30 ahadith (umdah al ahkām) Now , almost 150 Alhamdulillah But, my himmah has dropped so low, sins and forgetfulness, what to do now? It used to be more than 5 ahadith a day, but now 2 or even 0 some days Is it sins

It could be from sins, and it could also be from lack of revision. This is the story of everyone, the himmah is strong at times and it drops at other times. The Prophet ﷺ said that every action has a period of zeal and every zeal has a slackening, and whoever's zeal is towards his Sunnah has succeeded (reported by Ahmad, its chain graded sahih by al-Albani rahimahullah). If the slackening takes you into leaving obligations or falling into what is haram, that is a sin to repent from, and if your obligations are intact and only your daily portion has dropped, then it is a passing thing. Do not stop, keep going even if it is two a day, and ask Allah much to help you upon the memorisation of the ahadith of His Messenger ﷺ.
