Hadith 16

sed obligations, when you forget it, then remember it after the time, wash; and if you do not find the water, perform Tayammum, then if you find the water, upon you is the repeating. And eleven washings are Sunnah – washing of the two Eids, and the Friday, and washing of Al-Ihraam, and day of Arafaah (9th Zilhajj), and entering Makkah, and entering Al-Medina, and Ziyaarah of the House (Kabah), and three nights from the month of Ramazan – night of 19th, and night of 21st, and night of 23rd. And when he forgets one of these, or is desperate, or there is an illness with him preventing him from the washing, there is no repeating upon him; and the leases of what suffices you and sufficient for you from the water is water your body can be wetted with, like the oil; and Rasool-Allah-saww and one of his-saww wives had washed with a ‘Sa’a’ of water’’. [23]
And it is reported that recommended washing is on night of the 21st (of month of Ramazan) because it is the night in which Isa Ibn Maryam-as was Raised, may the Salawaat of Allah-azwj be upon him-as, and Amir Al-Momineen Ali-asws was buried, and with them it is ‘Laylat Al-Qadr’, and the night of the 23rd, it is the night in which it is hoped for’’. [24]
And Abu Abdullah-asws had said: ‘When the man fasts 23rd from a month of Ramazan, it is allowed for him if he goes and comes in his journeys, and night of 19th from a month of Ramazan, it is which our-asws grandfather-asws Amir Al-Momineen-asws, may the Salawaat of Allah-azwj be upon him-asws, was struck, and the washing is recommended during it’’. [25]
And he-asws said: ‘When the dawn of the day of Eid emerges, then wash, and it is the first timing of the washing, then to the time of midday’’. [26]
