What is the ruling on the martyr's intercession on the day of Resurrection?

All perfect praise be to Allaah, the Lord of the worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His Slave and Messenger.

Authentic Hadeeths indicate there will be intercession from the martyrs, each according to his rank and degree in the Sight of Allaah.

For example a Hadeeth narrated by Abu Ad-Dardaa’ on the authority of the Prophet, sallallaahu ‘alayhi wa sallam, states that the martyr will intercede for 70 from his household. [Ibn Hibbaan. Al-Albaani: Saheeh (Authentic)]

There is another Hadeeth narrated on the authority of the Prophet, sallallaahu ‘alayhi wa sallam, that also indicates that the angels, prophets and martyrs will be permitted to intercede [Ahmad. Shu‘ayb Al-Arna’oot: Hasan (Sound)]

Allaah Knows best.
