tahir-ul-qadri is doing nothing but reviving a biddat. The hadeeths quoted in above fatwa can only be used to advise a person to recite Kalima on the dead bed (while still alive), not after a person death.
Lets see what Quraan says on this issue:
There are two unequivocal texts from the Qur'an which deny the possibility of the dead in their graves possessing the faculty of hearing. Allah, the Blessed and Exalted, states :
[Surah an-Naml 27:80]
إِنَّكَ لَا تُسْمِعُ الْمَوْتَىٰ وَلَا تُسْمِعُ الصُّمَّ الدُّعَاءَ إِذَا وَلَّوْا مُدْبِرِينَ
Yusuf Ali 80: Truly thou canst not cause the dead to listen, nor canst thou cause the deaf to hear the call, (especially) when they turn back in retreat.
البتہ تو مردوں کو نہیں سنا سکتا اور نہ بہروں کو اپنی پکارسنا سکتا ہے جب وہ پیٹھ پھیر کر لوٹیں
[Surah Fatir 35:22]
وَمَا يَسْتَوِي الْأَحْيَاءُ وَلَا الْأَمْوَاتُ ۚ إِنَّ اللَّهَ يُسْمِعُ مَن يَشَاءُ ۖ وَمَا أَنتَ بِمُسْمِعٍ مَّن فِي الْقُبُورِ
Yusuf Ali 22: Nor are alike those that are living and those that are dead. Allah can make any that He wills to hear; but thou canst not make those to hear who are (buried) in graves.
اور زندے اور مردے برابر نہیں ہیں بے شک الله سناتا ہے جسے چاہے اور آپ انہیں سنانے والے نہیں جو قبروں میں ہیں
In the first verse Allah addresses His messenger, Muhammad (صلى الله عليه وسلم)
, reminding him that he cannot make the disbelievers hear the invitation to Islam, for they are like the dead, who do not hear either. In the second verse Allah points to the difference between the living and the dead - they are not all alike. He further clarifies to His prophet (صلى الله عليه وسلم)
that he cannot make the rejectors of faith hear the message (for they are dead in heart and in spirit) any more than he (صلى الله عليه وسلم)
can make those in the graves hear what is spoken to them!
