Sister Amat-Allah, if you can't keep promises it's better to not make any at all then (like sister SomaliSizz said)...I know a sister that used to do that or like brother LionHeart-112 said, have the intentions of keeping it

Miss~Bl!ss, you're welcome and shuukran sis
SoMaLiSiZz, Wa feeke (lol, did I get it right?

LionHeart-112, Ameen do your du'a

Salam
