As Salaamu Alaikum Wa Rahmutallahi Wa Baraakaatahu,
In these times of Covid -19, we find that the focus especially is centred around remaining clean and washing hands. It must be pointed out that this was also given the upmost importance 1,400 years ago; in the time of Allah's messenger (ﷺ) and his companions. The hadeeth above brings many beautiful benefits, and should act as a staunch reminder as to why we should pay great attention to the Wudhoo of the Muslim.
What do we take from this hadeeth:
1) First and foremost, this hadeeth shows the station of the Wudhoo and its importance. The wudhoo is a reason for a person on Yawmul Qiyaamah to have light beaming from him/her, at a time when there will be complete darkness surrounding them.
2) The term "غُرًّا مُحَجَّلِينَ", are white marks, also referred to as a "لعمة" in the arabic language; referring to the white mark on the forehead of the horse; generally considered to be a beautiful marking upon the horse.
3) The ablution of Al Wu'dhoo is specifically for the Ummah of Muhammad (ﷺ) and it was not practiced in the previous nations and that is the reason why Allah سبحانه وتعالى has placed light in the face of the Muslim on the day of judgement. Shaikh Al Islaam Ibn Tamiyaah, mentions that the wudhoo is specified only for this Ummah of Muhammad (ﷺ) , and this is mentioned in the hadeeth found in Saheeh Muslim.
Abu Huraira reported:.......They said: Messenger of Allah, will you recognise us on that day? He said: Yes, you will have distinctive marks which nobody among the peoples (except you) will have; you would come to me with blazing forehead and bright hands and feet on account of the traces of ablution.
قَالُوا يَا رَسُولَ اللَّهِ أَتَعْرِفُنَا يَوْمَئِذٍ قَالَ " نَعَمْ لَكُمْ سِيمَا لَيْسَتْ لأَحَدٍ مِنَ الأُمَمِ تَرِدُونَ عَلَىَّ غُرًّا مُحَجَّلِينَ مِنْ أَثَرِ الْوُضُوءِ "
Sahih Muslim 247a
4) Another benefit that can be taken from this hadeeth is that obedience to Allah سبحانه وتعالى is the reason for happiness and success in this life and the hereafter and every act of worship for Allah has its reward.
5) The saying of the Prophet Muhammad (ﷺ) .
" إِنَّ أُمَّتِي " - meaning "My Ummah!" is referring to the nation of Muslims on the day of judgement. The term Ummah consists of two definitions; (1) Ummah Al Dawah and (2) Ummah Al ijaabah. The Ummah Al Dawah refers to the Non-Muslims who are in need of dawah and guidance to Al Islaam and the Ummah Al-Ijaabah, refers to the Muslims who have answered the call of the Prophet Muhammad (ﷺ). In the hadeeth, it is referring to the those muslims who followed the commands of the Prophet (ﷺ) and remained upon Tawheed and practiced his sunnah in there lives.
May Allah make us from those who come on the day of judgement, with bright faces, seeking the good pleasure of our Lord, Rubbul -Alameen.
