[16].Surah An-Nahl [The Bees] : Ayat 90

Ayat 90. Verily, Allah enjoins Al-Adl (i.e. justice and worshipping none but Allah Alone - Islamic Monotheism) and Al-Ihsan [i.e. to be patient in performing your duties to Allah, totally for Allah's sake and in accordance with the Sunnah (legal ways) of the Prophet  [SAWW](PBUH) in a perfect manner], and giving (help) to kith and kin (i.e. all that Allah has ordered you to give them e.g., wealth, visiting, looking after them, or any other kind of help, etc.): and forbids Al-Fahshâ' (i.e all evil deeds, e.g. illegal sexual acts, disobedience of parents, polytheism, to tell lies, to give false witness, to kill a life without right, etc.), and Al-Munkar (i.e all that is prohibited by Islamic law: polytheism of every kind, disbelief and every kind of evil deeds, etc.), and Al-Baghy (i.e. all kinds of oppression), He admonishes you, that you may take heed. 

Hazrat Abu Hurairah (May Allah be pleased with him) reported: Messenger of Allah  [SAWW](PBUH) said, "Allah created all the creatures and when He finished the task of His creation, Ar-Rahm (ties of relationship) said: `(O Allah) at this place I seek refuge with You against severing my ties.' Allah said: `That I treat with kindness those who treat you with kindness and sever ties with those who sever ties with you.' It said: `I am satisfied.' Allah said: `Then this is yours". Then Messenger of Allah  [SAWW](PBUH) said, "Recite this Ayah if you like: `Would you then, if you were given the authority, do mischief in the land, and sever your ties of kinship? Such are they whom Allah has cursed, so that He has made them deaf and blinded their sight". (47:22,23).

[Al-Bukhari Book 08, Chapter 73, Hadith # 16].

The words in another narration in Al-Bukhari are: Messenger of Allah  [SAWW](PBUH) said, "Allah (SWT) says: `He who maintains good ties with you, I maintain good ties with him; and he who severs your ties, I sever ties with him".

[Al-Bukhari Book 08, Chapter 73, Hadith # 17]. 

Lesson : as mentioned above in Surah An-Nahl Ayat 90. and giving (help) to kith and kin (i.e. all that Allah has ordered you to give them e.g., wealth, visiting, looking after them, or any other kind of help, etc.) This Hadith also stresses the importance of proper treatment with relatives for the reason that this is a special means of attaining the nearness and Mercy of Allah. A conduct contrary to it, that is to say, devouring the rights of relatives and continuation of estrangement with them, is the cause of displeasure and Wrath of Allah.
