وَعَنِ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا
قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَنْ فُتِحَ لَهُ مِنْكُمْ بَابُ الدُّعَاءِ فُتِحَتْ لَهُ أَبْوَابُ الرَّحْمَةِ وَمَا سُئِلَ اللَّهُ شَيْئًا يَعْنِي أَحَبَّ إِلَيْهِ مِنْ أَنْ يُسْأَلَ الْعَافِيَةَ»
The Prophet (sallallahu alayhi wa sallam) said:, “If the gate of supplication is opened for any of you, the gates of mercy will be opened for him, and God is not asked for anything He likes so much as to be asked for security.”
