So, [O Muḥammad], We have only made it [i.e., the Qur’ān] easy in your tongue [i.e., the Arabic language] that you may give good tidings thereby to the righteous and warn thereby a hostile people.
Allah places Love of the Righteous People in the Hearts
Allah, the Exalted, informs about His believing servants, who work righteous deeds -- deeds that He is pleased with because they are in accordance with the legislation of Muhammad -- that He plants love for them in the hearts of His righteous servants. This is something that is absolutely necessary and there is no avoiding it. This has been reported in authentic Hadiths of the Messenger of Allah ﷺ in various different ways. Imam Ahmad recorded that Abu Hurayrah said that the Prophet said,
"For them the Rahman (All-Merciful) will create love." - 19:96.
It means that for those who are steadfast in their faith in Him, Allah creates an environment of friendship and love for each other, which consequently promotes mutual amity and goodwill among the true Muslims. Furthermore, by their conduct and behavior they command the admiration and respect of all those with whom they come into contact. Bukhari, Tirmidhi and others have related on the authority of Sayyidna Abu Hurairah ؓ that the Holy Prophet ﷺ once said that when Allah Ta’ ala is pleased with someone He says to Jibra'il (علیہ السلام) ، "I am pleased with so and so and I desire that you too should show favour to him." Jibra'l (علیہ السلام) makes an announcement to this effect in all the skies so that their residents begin to harbor a liking for that person. Then this love descends upon the earth and the people of the earth also begin to love him. The Holy Prophet ﷺ then quoted this verse. (Ruh ul-Ma’ ani).
It often happens that those who espouse the cause of unadulterated truth invite the wrath of the upholders of falsehood. Indeed, they become objects of hatred even in their own communities. But, in the life hereafter, the position will be reversed: the entire atmosphere will favour those devoted upholders of the pure and unadulterated truth; here in this world, having eschewed worldly honour and popularity in their staunch support of the truth, they will find in the afterlife, that they are rewarded with the highest possible esteem.
