Dear,, respected readers..
I feel curious after reading some Hadists then I try to write the deep rewards of doing fasting on the day of Arafah.
On the authority of Abū Qatādah al-Anṣārī (1):
…The Messenger of Allāh, prayers and peace upon him, was asked about fasting on The Day of ‘Arafah. [He, prayers and peace upon him, replied]: ‘Fasting on the day of‘Arafah is an expiation of last year’s and next year’s sins.’ [Collected by Muslim/#1162]
[Issues Pertaining to this Prophetic Tradition]
: What is ‘Arafah?
Shaykh al-‘Uthaymīn [d. 1421 AH], may Allāh have mercy on him, said:
‘Arafah is a well-known place related to the rites of Ḥajj, and standing at ‘Arafahis a pillar of Hajj [i.e. it is something that the pilgrim must do]…The Messenger of Allāh said: ‘Hajj is ‘Arafah.’ (2)/(3)
: What is The Day of ‘Arafah?
He (Shaykh al-‘Uthaymīn), may Allāh have mercy on him, also said:
The Day of ‘Arafah is the ninth of Thūl Ḥijjah according to the Islamic calendar. It has been named The Day of ‘Arafah because it is the day when all pilgrims stand at ‘Arafah. (4)
: Benefits from This Prophetic Tradition:
Shaykh al-‘Uthaymīn [d. 1421 AH], may Allāh have mercy on him, said (summarized): Some benefits of this Prophetic practice are what follows:
1. The diligence of the Companions in seeking beneficial knowledge
2. The rewards for performing an action are of two types:
a.) [you will] be given something desirable; or
b.) [you will] have something undesirable removed.
The reward for fasting The Day of ‘Arafah is of the second type (i.e. having something undesirable removed) due to the statement of the Messenger of Allāh: ‘Fasting the day of ‘Arafah is an expiation of last year’s sins.’
3. It is possible for past, as well as future sins to be expiated… (5)
