Many of us sometimes swear by Allah's name and take oaths lightly but have you heard what our Prophet said in this regard? The Prophet (peace be upon him) said: If anyone swears a false oath in confinement, he should make his seat in Hell on account of his (act).
Dawud: Book 21, Hadith 3236
Point to be noted don't ever take an oath and break it! Fear your Creator.
