The scholar AbulBaqaa’ Ibrahim bin Husain bin Ibrahim Al-Raqaa Al-Basrl narrated from Abu TalebYahya bin Mohammad bin Husain bin O’tba, from Abul Husain Mohammad bin Ahmad bin Khalid Al-Mathaari, from the scholar Abu Mohammad Harun bin Musa bin Ahmad Al-Talakabari, from Abul Husain Mohammad bin Ahmad bin Makhzood servant of BaniHashim, from Hasan bin Ahmad bin Abdul Ghaffar Al-Ansari, from Ahmad bin Mohammad bin Malik, from Yazid bin Harun, from Hameed Al-T’aweel, from AbiZorarah, from Ibn Abbas, who said:
I heard the MESSENGER OF ALLAH (SAWW) tell ALI BIN ABITALEB(ASWS) to wear an AQEEQ (agate) ring on his right hand because those who wear it have a quality that ALLAH (SWT) has given to those who are close to Him.
Ali (ASWS) asked the Prophet (ASWS) “Who are those who are close to ALLAH (SWT)?” The Prophet (SAWW) replied, “Jibraeel, Mikaeel, and the angels between them.” Ali (ASWS) asked, “What kind of Aqeeq should I wear?”
The Prophets replied, “Choose the red Aqeeq because the mountain of the red Aqeeq testified that there is no god but ALLAH (SWT), that I am the MESSENGERof ALLAH (SWT), that you are my heir, that your sons are the Imams, that your Shia will go to Paradise, and that those who hate them will go to Hell.”
