Chapter on Oaths, Vows, and Expiations
Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 2|Chapter 38
وَ قَالَ رَسُولُ اَللَّهِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ: "مَنْ أَجَلَّ اَللَّهَ أَنْ يَحْلِفَ بِهِ كَاذِباً أَعْطَاهُ اَللَّهُ عَزَّ وَ جَلَّ خَيْراً مِمَّا ذَهَبَ مِنْهُ ".
The Messenger of Allah سبحانه وتعالى (peace be upon him and his family) said: "Whoever reveres Allah سبحانه وتعالى and refrains from swearing a false oath by Him سبحانه وتعالى, Allah سبحانه وتعالى, the Almighty and Glorious, will grant him something better than what he has lost."
