بسم الله الواحد القهار
Sheikh Hadi An-Najafi:
Al-Barqi narrated from Ibn Abi Najraan and Al-Bazanti both from Aasim Ibn Humayd, from Abu Baseer from one of them(5th or 6th Imam عليهما السلام) having said: ‘When the Believer dies, six images enter along with him into his grave. Among these is an image which is the most beautiful of them of face, well-built of the bodies, most aromatic of aromas, and cleanest of the images. So an image pauses on his right, and another on his left, and another in front of him, and another behind him, and another by his feet, and the one which is the most beautiful of these, pauses by his head. So if he is approached (by anything bad) from his right, that which is on his right prevents it. Such is that case from all six sides.
The Imam(عليه السلام) said: ‘So the one of the most beautiful of these images, says: ‘Who are you, may Allah Recompense you goodly?’ So the one on the right of the servant says: ‘I am the Salaat’, and that which is on his left says, ‘I am the Zakat’, and that which is in front of him says: ‘I am the Fasts’, and the one which is behind him says, ‘I am the Hajj’, and that which is by his feet says: ‘I am the righteousness which you did to your brothers’. Then they (all) say: ‘Who are you? – for you are the most beautiful of faces, and most aromatic of aromas, and most well-built of body’. So it says: ‘I am the Wilayah of the Progeny of Mohammad(عليهم السلام)’.
The chain of narrators of the hadith is Sahih(authenic).
