Hadith on Mercy: Show mercy to those on the earth, Allah will have mercy on youحديث عن الرحمة : ارحموا من في الأرض يرحمْكُم من في السّماءِ

Abdullah ibn Amr reported: The Messenger of Allah, peace and blessings be upon him, said, “Those who are merciful will be shown mercy by the Merciful. Be merciful to those on the earth and the One above the heavens will have mercy upon you. The womb is derived from the Merciful, so whoever keeps relations with his family then Allah will keep relations with him, and whoever abandons his family then Allah will abandon him.”

عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو يَبْلُغُ بِهِ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ الرَّاحِمُونَ يَرْحَمُهُمْ الرَّحْمَنُ ارْحَمُوا مَنْ فِي الْأَرْضِ يَرْحَمْكُمْ مَنْ فِي السَّمَاءِ الرَّحِمُ شُجْنَةٌ مِنْ الرَّحْمَنِ فَمَنْ وَصَلَهَا وَصَلَهُ اللَّهُ وَمَنْ قَطَعَهَا قَطَعَهُ اللَّهُ
