بِسْمِ اللّهِ الرَّحْمـَنِ الرَّحِيمِ
Part of Al-Baqarah (The Cow) - 2:143....behold, God is most compassionate towards people, a Dispenser of Grace"
Be kind to people, for your Lord is Kind
A Muslim must be kind. Those whose Lord is named ٱلْرَّحْمَـٰنُ (’Ar-Raḥmaān/The Most Gracious) and ٱلْرَّحِيْمُ(’Ar-Raḥīm/The Most Merciful) , and whose Prophet(ﷺ), is the Prophet(ﷺ) who was not sent except as رَحْمَةً لِّلْعَالَمِينَ (Mercy to the worlds), can they be anything other than kind?
A story is narrated by Shaykh Mukhtar Al-Kunti in his book Fath al-Wadud, page 358-359:
It is mentioned that once an idolater became a guest of Ibrahim (عليه السلام), (and before providing him with food), the prophet realized that he was an idolator and thus sent him off. Angel Gabriel(عليه السلام) appeared and said to Ibrahim (عليه السلام), "I bring the greeting of peace from your Lord, who asks you, 'Why did you turn away my servant?'"
Ibrahim (عليه السلام) replies, "Because he was an idolater/polytheist."
"God asks you, 'Did you create him or did I ?'"
Ibrahim (عليه السلام) replies, “Of course, You (God) created him.”
"God asks you, 'Was his disbelief in Me or in you?'"
Ibrahim (عليه السلام) responds, “His disbelief was in You.”
"God asks you, 'Did you provide for him all these years or was I?'"
Ibrahim (عليه السلام), “Indeed, You are my provider as well as his.”
"God asks, ‘Did He create that disbelief in his heart, or did you create it in him and nurture it?'"
Ibrahim (عليه السلام) says, “No, You did.”
"God asks you whether his disbelief harms him or does it harm you?"
Ibrahim (عليه السلام) replies, "No, it harmed him."
"God says, 'If that is the case, then why did you deprive My servant, and your brother? For he is in one of two possible conditions: either he is condemned to be fuel for the Fire and the object of My wrath, or I can forgive him and make him among those who are my beloveds and grant him peace in the abode of My Mercy.'"
Hearing this, Ibrahim (عليه السلام)went out in search of the man and found he was now fearful of him. He showed the man kindness and persuaded him into returning to his tent so that he may take care of him, and feed him. The man said, "Something has happened, as you are acting so differently towards me. Initially you refused me, and now you are showing me kindness, as if you want something from me."
Ibrahim (عليه السلام) said to him, “My Lord reproached me for the way I treated you.”
To this the man said, “What a blessed Lord you have that He should reproach His beloved friend on account of to his bad behavior toward His enemy.” He then submitted to the God of Ibrahim (عليه السلام) and worshipped with him until he died.
A similar story is mentioned in the risalah of Qushayri, although not in so much detail.
