2. But Dua from anyone other than Allah is not permissible. Dua is an IBADAT that can be done only for Allah.
When one uses Tawassul in supplication, one does not ask and seek from other than Allah.
1.All Islamic Scholars (Sunni and Salafi) are agreed that dua is an Ibadah that can be done to Allah Alone and to no one else.
Allah Ta’ala says in surah al fatiha, ‘إِيَّاكَ نَعْبُدُ وَإِيَّاكَ نَسْتَعِينُ (5)’.
Our Prophet [sallallaahu alayhi wasallam] said to Hadhrat Ibn Abbas radhiallaahu anhu;
إِذَا سَأَلْتَ فَاسْأَلِ الله وَإِذَا اسْتَعَنْتَ فَاسْتَعِنْ بِالله (رواه أحمد و الترمذى و ابن أبى الدنيا)
‘When you ask, ask Allah and when you need help, seek help from Allah’
Also Dua is an Ibadah (form of worship) as mentioned in the understated hadith of Anas ibn Malik radhiallaahu anhu. So when a person makes dua to a deceased person, it is as though he/she is worshipping him/her therefore it is not permissible.
It is narrated by Hadhrat Anas radhiallaahu anhu,
عَنْ أَنَسِ بْنِ مَالِكٍ عَنِ النَّبِيِّ صَلَّى الله عَلَيْهِ وَسَلَّمَ قَالَ: «الدُّعَاءُ مُخُّ العِبَادَةِ» (رواه سنن الترمذى)
‘Supplication is the essence of worship’
In another version, “الدعاء هو العبادة” “Dua is Ibadah”
3. Grave worship in all its form is being condemned by all scholars of Islam, no scholar is permitting it.
4. Majority of the scholar based on Hadith of Sayyiduna Uthmaan ibn Hunayf [radhiallaahu anhu](Musnad Ahmad vol.4 pg.138; Sunan Tirmidhi; Sunan ibn Majah; Mustadrak Haakim and others).
Imaams Tirmidhi, ibn Khuzaymah and Haakim have classified this Hadith as authentic and other Ahadith has Permitted to take waseela from Prophet Muhammad Sallallahu Alaihi Wasallam and Aulia Allah.
5.No one should mix Grave Worship in all its form with the original issue of taking Waseela in Dua.
6. Taking Waseela in Dua is pure Islam and Grave Worship in all its form is pure shirk.
