The root ل ح ق (l-ḥ-q) in the Quran

فَرِحِينَ بِمَآ ءَاتَىٰهُمُ ٱللَّهُ مِن فَضْلِهِۦ وَيَسْتَبْشِرُونَ بِٱلَّذِينَ لَمْ يَلْحَقُوا۟ بِهِم مِّنْ خَلْفِهِمْ أَلَّا خَوْفٌ عَلَيْهِمْ وَلَا هُمْ يَحْزَنُونَ ۝١٧٠

Rejoicing in what Allāh has bestowed upon them of His bounty, and they receive good tidings about those [to be martyred] after them who have not yet joined them - that there will be no fear concerning them, nor will they grieve.

رَبِّ قَدْ ءَاتَيْتَنِى مِنَ ٱلْمُلْكِ وَعَلَّمْتَنِى مِن تَأْوِيلِ ٱلْأَحَادِيثِ فَاطِرَ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ أَنتَ وَلِىِّۦ فِى ٱلدُّنْيَا وَٱلْـَٔاخِرَةِ تَوَفَّنِى مُسْلِمًا وَأَلْحِقْنِى بِٱلصَّٰلِحِينَ ۝١٠١

My Lord, You have given me [something] of sovereignty and taught me of the interpretation of dreams. Creator of the heavens and earth, You are my protector in this world and the Hereafter. Cause me to die a Muslim and join me with the righteous."

رَبِّ هَبْ لِى حُكْمًا وَأَلْحِقْنِى بِٱلصَّٰلِحِينَ ۝٨٣

[And he said], "My Lord, grant me authority and join me with the righteous.

قُلْ أَرُونِىَ ٱلَّذِينَ أَلْحَقْتُم بِهِۦ شُرَكَآءَ كَلَّا بَلْ هُوَ ٱللَّهُ ٱلْعَزِيزُ ٱلْحَكِيمُ ۝٢٧

Say, "Show me those whom you have attached to Him as partners. No! Rather, He [alone] is Allāh, the Exalted in Might, the Wise."

وَٱلَّذِينَ ءَامَنُوا۟ وَٱتَّبَعَتْهُمْ ذُرِّيَّتُهُم بِإِيمَٰنٍ أَلْحَقْنَا بِهِمْ ذُرِّيَّتَهُمْ وَمَآ أَلَتْنَٰهُم مِّنْ عَمَلِهِم مِّن شَىْءٍ كُلُّ ٱمْرِئٍۭ بِمَا كَسَبَ رَهِينٌ ۝٢١

And those who believed and whose descendants followed them in faith - We will join with them their descendants, and We will not deprive them of anything of their deeds. Every person, for what he earned, is retained.

وَءَاخَرِينَ مِنْهُمْ لَمَّا يَلْحَقُوا۟ بِهِمْ وَهُوَ ٱلْعَزِيزُ ٱلْحَكِيمُ ۝٣

And [to] others of them who have not yet joined them. And He is the Exalted in Might, the Wise.
