The Meaning: What is meant from favour here is the performance of an act with the intention to assist a Muslim; irrespective of whether the act results in bringing about gain or removal of harm in actuality. A case of this would be when a person intends to put out a fire in a house belonging to a Muslim, and in the process he breaks a wall of the house, in this case, whether the fire was put out or not, the assistance would be judged on the intended goodness in accordance with this Precept. Thus there will be no liability or blame on the person who is involved in causing harm to the property while intending to do good to it. .
The Sources: It is possible to demonstrate the worth of the Precept by the following: .
I. The Verse: His words, the most High " It shall be no crime for the weak, nor sick, nor for those who do not find what they should spend (to stay behind), so long as they are sincere to Allah and His Apostle; there is no way (to blame) against the doers of good; and Allah is Forgiving, Merciful;" .
This verse, even though it was revealed regarding the weak and unable with regard to Jihad, cannot be restricted to the cause of its revelation due to the end of the verse being general, "there is no way (to blame) against the doers of good;" .
This indicates the negation of blaming anyone who does good deeds to others. We deduce the lack of the liability to recompense or other liability against anyone who causes harm or loss to the property of another while intending a good act, from the unrestricted nature of the ending part of the verse .
And the Verse: "is the return for goodness save goodness" The verse indicates upon the negation of transgression and evil in the case of one intending to help and doing a favour to another, and indicates al priori (al-awlawiyyah) lack of liability. .
II. Concurrence of Opinion (Al-Tasalum): Concurrence of opinion has occurred among the scholars regarding the meaning indicated by this Precept, there is no opinion to be found stating its contrary viz. that any liability is incurred by the one who does a favour.
The certain extent of the Precept is the lack of liability for one who causes loss or damage to the property of another while not being designated to look after it, but does so through concern, otherwise it would not be considered as a favour.
