وَلَوْلَآ أَن كَتَبَ ٱللَّهُ عَلَيْهِمُ ٱلْجَلَآءَ لَعَذَّبَهُمْ فِى ٱلدُّنْيَا ۖ وَلَهُمْ فِى ٱلْءَاخِرَةِ عَذَابُ ٱلنَّارِ

Narrated `Abdullah Al Muzam:
The Prophet (ﷺ) said, "Perform (an optional) prayer before Maghrib prayer." (He repeated it thrice) and the third time he said, "Whoever wants to offer it can do so," lest the people should take it as a Sunna (tradition). (See Hadith No. 277, Vol. 2)
