Allaah subhaan’nahu wa’ta’aala says:
إن الذين آمنوا وعملوا الصالحات سيجعل لهم الرحمن ودّا
“Indeed, those who have believed and done righteous deeds – the Most Merciful will appoint for them affection.”
(Surat Maryam, 19:96)
Mujahid (scholar of tafseer & student of Ibn Abbas) said in explanation of this verse:
“Allaah loves them and makes them loved to His believing slaves” ¹
Imam Sa’aadi (rahimahullaah) said in explanation of this verse:
“This is from His blessings upon his slaves. The ones who combine between emaan and good deeds, that he promises to make for them affection: meaning love and affection (for them) in the hearts of His awliyaa, and those of the heavens and earth. And if there is affection in those hearts for them, then many of their affairs become easy, good things happen to them, supplications, guidance, acceptence and positions of authority.“ ²
¹Mujahid’s statement was taken from Tafseer Baghawi
²Imaam Sa’aadi’s is found in his tafseer of the Quran

By Shaykh ‘Abdul Muhsin Al-‘Abbad
[Translated by Abdulilah Lahmami]
It has been established that the Messenger (sallAllaahu ‘alayhi wa sallam) said,
“Whoever calls to guidance will have the reward similar to all those who follow him without their reward diminishing in any way and whoever calls to misguidance, he will have the sins similar to all those who follow him without their sins decreasing in any way.”
[Saheeh Muslim (4/2060)]
Commentary:
This noble hadeeth primarily necessitates a great portion and fortune for the Companions because they are the ones that took this guidance and light from the Messenger (sallAllaahu ‘alayhi wa sallam) and passed it on to those after them. So all those that benefited from it, the Companions (radiAllahu anhum) will have reward similar to theirs until Allaah inherits the earth and those upon it.
Yet before them, the Messenger (sallAllaahu ‘alayhi wa sallam), (since) he came with this good and this guidance, Allaah will reward His Prophet (sallAllaahu ‘alayhi wa sallam) with the same reward as He gives to all those who were guided, entered the religion of Allaah and did good deeds, without their reward decreasing in any way. This is because the Prophet (sallAllaahu ‘alayhi wa sallam) is the one who called the people to this guidance. He has the same reward of all those who benefited from it due to him, may Allaah’s blessing be upon him.
The Companions of the Messenger of Allaah (sallAllaahu ‘alayhi wa sallam) will have a great portion and fortune from that reward for they are the ones who obtained this guidance and passed it on to those after them. They are the ones who collected the Qur’an. They are the ones who memorised it. They are the ones who passed it on to those who came after them. Those who obtained the Sunnah of the Allaah’s Messenger (sallAllaahu ‘alayhi wa sallam), May Allaah be pleased with them. They passed it on to those who came after them thereby gaining much reward and recompense. They will receive a great reward and a great fortune from the call of the Messenger (sallAllaahu ‘alayhi wa sallam).

Regarding the hadeeth where the Prophet (sallAllahu ‘alayhi wa sallam) said:
“Do not look down on any act of kindness, even if it is just meeting your brother with a pleasant smile on your face.”
[Sahih Muslim]
Ibn ‘Uthaymeen said:
“A pleasant smile causes people to become happy, wins over their love and affection, and leads to both parties having good thoughts of each other. Just try it and you will see.
However, were you to frown upon the people, they would stay away from you and not feel comfortable sitting with you nor talking to you.
You may even become afflicted with a dangerous condition: high blood pressure. Having a tranquil chest and a pleasant smile is the most wholesome remedy and the best preventative measure for this condition. For this reason, physicians advice people who have this condition to stay away from what disturbs and angers them, since those things only agitate this condition.
A pleasant smile actually has a remedial effect on this condition, since it leads to a tranquil chest, and it causes others to love you.”
