As-salāmu ʿalaykum wa raḥmatullāhi wa barakātuhu If a Muslim abandoned obligatory ṣalāh for a long time out of laziness, then sincerely repents and begins praying regularly Must he make up the missed farḍ prayers, or is repentance alone sufficient? I know the four madhāhib require making them up.

Ustadh AbdulAziz al-Haqqan
Some of the people of ilm say there is no qadha' upon you and Allah knows best.
