1. Importance of Hajj


قَالَ عَلِيٌّ (ع): أَللٌّهُ أَللٌّهُ فِي بَيْتِ رَبِّكُمْ لاَ تَخْلُوهُ مَا بَقِيتُمْ فَإِنَّهُ إِنْ تُرِكَ لَمْ تُنَاظَرُوا.

Imam ‘Ali Ibn Abi Talib (peace be upon him) has said, “By Allah, by Allah, keep the House of your Lord in mind.  Do not disregard it as long as you remain (alive) because surely if it is ignored, then He shall not look towards you (with His Mercy).”
