Allah's Mercy will be shown only to those who are merciful; Show mercy to receive Mercy
"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."
قَالَ رَسُولُ اللَّهِ ﷺ الرَّاحِمُونَ يَرْحَمُهُمُ الرَّحْمَنُ ارْحَمُوا مَنْ فِي الأَرْضِ يَرْحَمْكُمْ مَنْ فِي السَّمَاءِ الرَّحِمُ شُجْنَةٌ مِنَ الرَّحْمَنِ فَمَنْ وَصَلَهَا وَصَلَهُ اللَّهُ وَمَنْ قَطَعَهَا قَطَعَهُ اللَّهُ
