mercy patience in the Quran

وَلَوْ أَنَّهُمْ صَبَرُوا حَتَّىٰ تَخْرُجَ إِلَيْهِمْ لَكَانَ خَيْرًا لَهُمْ ۚ وَاللَّهُ غَفُورٌ رَحِيمٌ ۝٥

If only they had patience until thou couldst come out to them, it would be best for them: but Allah is Oft-Forgiving, Most Merciful.

فَاصْبِرْ إِنَّ وَعْدَ اللَّهِ حَقٌّ ۚ فَإِمَّا نُرِيَنَّكَ بَعْضَ الَّذِي نَعِدُهُمْ أَوْ نَتَوَفَّيَنَّكَ فَإِلَيْنَا يُرْجَعُونَ ۝٧٧

So persevere in patience; for the Promise of Allah is true: and whether We show thee (in this life) some part of what We promise them,- or We take thy soul (to Our Mercy) (before that),-(in any case) it is to Us that they shall (all) return.

وَأَمَّا الْجِدَارُ فَكَانَ لِغُلَامَيْنِ يَتِيمَيْنِ فِي الْمَدِينَةِ وَكَانَ تَحْتَهُ كَنْزٌ لَهُمَا وَكَانَ أَبُوهُمَا صَالِحًا فَأَرَادَ رَبُّكَ أَنْ يَبْلُغَا أَشُدَّهُمَا وَيَسْتَخْرِجَا كَنْزَهُمَا رَحْمَةً مِنْ رَبِّكَ ۚ وَمَا فَعَلْتُهُ عَنْ أَمْرِي ۚ ذَٰلِكَ تَأْوِيلُ مَا لَمْ تَسْطِعْ عَلَيْهِ صَبْرًا ۝٨٢

"As for the wall, it belonged to two youths, orphans, in the Town; there was, beneath it, a buried treasure, to which they were entitled: their father had been a righteous man: So thy Lord desired that they should attain their age of full strength and get out their treasure - a mercy (and favour) from thy Lord. I did it not of my own accord. Such is the interpretation of (those things) over which thou wast unable to hold patience."

ثُمَّ إِنَّ رَبَّكَ لِلَّذِينَ هَاجَرُوا مِنْ بَعْدِ مَا فُتِنُوا ثُمَّ جَاهَدُوا وَصَبَرُوا إِنَّ رَبَّكَ مِنْ بَعْدِهَا لَغَفُورٌ رَحِيمٌ ۝١١٠

But verily thy Lord,- to those who leave their homes after trials and persecutions,- and who thereafter strive and fight for the faith and patiently persevere,- Thy Lord, after all this is oft-forgiving, Most Merciful.
