عَنْ عُثْمَانَ (بْنِ عَفَّانَ) رَضِيَ اللَّهُ عَنْهُ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ: ((مَنْ عَلِمَ أَنَّ الصَّلَاةَ حَقٌّ وَاجِبٌ دَخَلَ الْجَنَّةَ))
It is narrated from Sayyiduna Uthman bin Affan (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Whoever realizes that prayer is a right and an obligation will enter Paradise.
