 Why did they not accompany? (L-3071)

بَلْ ظَنَنتُمْ أَن لَّن يَنقَلِبَ ٱلرَّسُولُ وَٱلْمُؤْمِنُونَ إِلَىٰٓ أَهْلِيهِمْ أَبَدًا وَزُيِّنَ ذَٰلِكَ فِى قُلُوبِكُمْ وَظَنَنتُمْ ظَنَّ ٱلسَّوْءِ وَكُنتُمْ قَوْمًۢا بُورًا 12  وَمَن لَّمْ يُؤْمِنۢ بِٱللَّهِ وَرَسُولِهِۦ فَإِنَّآ أَعْتَدْنَا لِلْكَٰفِرِينَ سَعِيرًا 13  وَلِلَّهِ مُلْكُ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ يَغْفِرُ لِمَن يَشَآءُ وَيُعَذِّبُ مَن يَشَآءُ وَكَانَ ٱللَّهُ غَفُورًا رَّحِيمًا 14

12.  Bal  zanantum  ‘allany-yanqalibar-Rasuulu  wal-Mu'-minuuna  ‘ilaaa  ‘ahliihim  ‘abadanw-wa  zuyyina  zaalika  fii  quluubikum  wa  zanantum  zannnas-saw-'i  wa  kuntum  qawmam- buuraa. 13.  Wa  mal-lam  yu'-mim- Billaahi  wa  Rasuulihii  fa-‘innaaa  ‘a'-tadNaa  lil-kaafiriina  Sa-'iiraa. 14.  Wa  Lillaahi  Mulkus-samaawaati  wal-‘arz.  Yagfiru  limany-yashaaa-'u  wa  yu-'azzibu  many-yashaaa'.  Wa  kaanAllaahu  Gafuurar-Rahiimaa.

12. Nay, but you deemed that the messenger and the believers would never return to their own folk, and that was made fair-seeming in your hearts, and you did think an evil thought, and you were worthless folk. 13. And so for him who believes not in Allah and His messenger - Lo! We have prepared a flame for disbelievers. 14. And Allah's is the Sovereignty of the heavens and the earth. He forgives whom He will, and punishes whom He will. And Allah is ever Forgiving, Merciful.

It is commanded: They tell a lie that there was no protector of their wealth and families at home behind them, so they could not go along with you. Purpose of their remaining behind was that they considered the Muslims as nothing. They were thinking that the Messenger (grace, glory, blessings and peace be upon him) and his Believers would be slain by the people of Makkah and they would never return, and they desired the same.

But the Muslims returned from Makkah successfully, and Allaah Almighty was Aware that these hypocrites would be destroyed instead of the Muslims. Listen carefully! We have prepared the Fire for them who do not believe in Allaah Almighty and His Messenger (grace, glory, blessings and peace be upon him). Reply of your request - asking forgiveness for you - is it that Allaah Almighty has all such Powers, because to Him belongs the Dominion of the heavens and the earth. He forgives whom He wills and punishes whom He wills. He will forgive you if you repent with true hearts. He is Forgiving and Merciful.
