Istigatha through Prophet peace be upon him on the day of judgement.
Narrated Abu Huraira:
The Prophet (ﷺ) got up amongst us and mentioned Al Ghulul (Dishonesty in war booty or Dishonesty in anything see Mirqaat al Mafateeh), emphasized its magnitude and declared that it was a great sin saying, “Don’t commit Ghulul for I should not like to see anyone amongst you on the Day of Ressurection, carrying over his neck a sheep that will be bleating, or carrying over his neck a horse that will be neighing. Such a man will be saying:
يَا رَسُولَ اللَّهِ أَغِثْنِي
O Allah’s Messenger (ﷺ)! Agithni
and I will reply,
لا أملك لك شيئا
‘I can’t help you, for I have conveyed Allah’s Message to you Nor should I like to see a man carrying over his neck, a camel that will be grunting. (I.e. the camel he stole or dishonesty borrowed)
Sahih al-Bukhari 3073
Mulla Ali al Qari said:
( ” يا رسول الله ! أغثني ” ) : أمر من الإغاثة والمراد منه الشفاعة ( ” فأقول : لا أملك ” ) أي : من الله ( ” لك ” ) أي : لأجلك ( ” شيئا ” ) أي : من الدفع والنفع ، والمعنى لا أدفع عنك شيئا من عذاب الله ( ” قد أبلغتك ” ) أي : وثبتت عليك الحجة فيما بين المؤمنين : ( وما على الرسول إلا البلاغ المبين )
O Rasool Allah help me) Igatha is (seegha of) Amr the meaning is Intercession. (I can’t help you)… Meaning I can’t push anything from Allah’s punishment against you. (I have conveyed) meaning I have established the hujjah against the Momineen (Allah says) The Messenger’s duty is only to deliver ˹the message˺ clearly.”
Mirqaat al Mafateeh under the hadeeth 2996
In short, this will happen when The Prophet peace be upon him is in front of you on the day of Judgement, what about asking him help in this world when He peace be upon him is not in front of you? For sure He peace be upon him will intercede on the day of judgement for the sinners. But what will happen to the extreme innovators and those who perform shirk.
