لسلام عليكم ورحمة الله وبركاته, احسن الله اليك if someone says wallah while while deliberately lying, does he have to fast 3 days or only repent? and what is the ruling on saying wallah while stating an opinion like „wallahi i’m better“? بارك الله فيك

Ustadh AbdulAziz al-Haqqan
No. But this is forbidden akhi and from the traits of hypocrites, so don't lie.
