Abdullah bin 'Amr narrated that the Messenger of Allah said: " The merciful are shown mercy by Ar-Rahman. Be merciful on the earth, and you will be shown mercy from Who is above the heavens. The womb is named after Ar-Rahman, so whoever connects it, Allah connects him, and whoever severs it, Allah severs him." [Hadith from Jami' at-Tirmidhi, English reference: Vol. 4, Book 1, Hadith 1924; Arabic reference: Book 27, Hadith 2049].
