In the following two Verses Allah -azwj further Says that they are aware of the affairs of those who they have left behind: فَرِحِينَ بِمَا آتَاهُمُ اللَّهُ مِنْ فَضْلِهِ وَيَسْتَبْشِرُونَ بِالَّذِينَ لَمْ يَلْحَقُوا بِهِمْ مِنْ خَلْفِهِمْ أَلَّا خَوْفٌ عَلَيْهِمْ وَلَا هُمْ يَحْزَنُونَ {1703:} يَسْتَبْشِرُونَ بِنِعْمَةٍ مِنَ اللَّهِ وَفَضْلٍ وَأَنَّ اللَّهَ لَا يُضِيعُ أَجْرَ الْمُؤْمِنِينَ {1713:} Rejoicing in what Allah has Given them from His Grace and they are receiving glad tidings of those whom have yet to join them from the ones they left behind.

Respecting ‘Shaa’ir Allah’ is also a ‘ Wasila ’ to approach Allah -azwj There are so many historical accounts of the miracles of ‘Shaa’ir Allah’ as well as from Ahadith but we will only confine to the Holy Verses, see for example Prophet Yusuf -as says: اذْهَبُوا بِقَمِيصِي هَٰذَا فَأَلْقُوهُ عَلَىٰ وَجْهِ أَبِي يَأْتِ بَصِيرًا وَأْتُونِي بِأَهْلِكُمْ أَجْمَعِينَ {93} Go with this shirt of mine and cast it upon my father’s face, he would regain his vision, and come to me with your family altogether’ [12:93] وَلَمَّا فَصَلَتِ الْعِيرُ قَالَ أَبُوهُمْ إِنِّي لَأَجِدُ رِيحَ يُوسُفَ ۖ لَوْلَا أَنْ تُفَنِّدُونِ {94} And when the caravan departed, their father said: ‘Surely, I find the aroma of Yusuf, unless you deem me to be weak minded’ [12:94] See some Holy Verses in Appendix III.

Appendix I: Holy Verses forbidding Self-Made ‘ Wasila ’ أُولَٰئِكَ الَّذِينَ يَدْعُونَ يَبْتَغُونَ إِلَىٰ رَبِّهِمُ الْوَسِيلَةَ أَيُّهُمْ أَقْرَبُ وَيَرْجُونَ رَحْمَتَهُ وَيَخَافُونَ عَذَابَهُ ۚ إِنَّ عَذَابَ رَبِّكَ كَانَ مَحْذُورًا {57} They, those they are calling (as per their wish), seeking the means to their Lord, which of them is closest? And they are hoping for His Mercy and fearing His Punishment.

Surely the Punishment of your Lord was always feared [17:57] Also, إِنَّ اللَّهَ لَا يَغْفِرُ أَنْ يُشْرَكَ بِهِ وَيَغْفِرُ مَا دُونَ ذَٰلِكَ لِمَنْ يَشَاءُ ۚ وَمَنْ يُشْرِكْ بِاللَّهِ فَقَدِ افْتَرَىٰ إِثْمًا عَظِيمًا {48} Surely, Allah does not forgive that anything (one) had associated with Him, and forgives what is besides that to whomsoever He pleases; and whoever associates anything with Allah, he devises indeed a great sin (4:48).
