Imam Qurtubi (rah) on Tawassul: “Abu Sadiq has reported it from ‘Ali. A villager came to see us three days after the burial of the Holy Prophet (Peace Be Upon Him). He placed himself near the Prophet’s grave, sprinkled its earth over his body and said: ‘O Messenger of Allah (Peace Be Upon Him), you said and we have heard it from you. You received commands from Allah and we received commands from you, and one of these divine commands is wa law annahum idh zalamu anfusahum. It is true that I have wronged myself, therefore, you should pray for my forgiveness.’ (In response to the villager’s act of imploring) he was called out from the grave: ‘there is no doubt that you have been forgiven.’” [Tafsir al-Qurtubi, al-Jami li Ahkam al-Quran Volume 006, Page No. 439, Under the Verse, 4:64] —- Abdullah Abdul al Muhsin Said: This hadith is narrated by Abu Sadiq (ra), Do you think that whos full name is Abu Sadiq Hu al Awazi al Kufi (ra), Abdullah bin Najiz said: Sadduq (Truthful), and This Hadith is Mursil (Jayyid)
Imam Qurtubi (rah) on Istigatha: Ibn Abbas (ra) said: “When the jews of khaybar was in war with the Creed of Gatfan, they was defeated and after they did say: “Allahumma! We want you to help us for your Nabi which you will send in the end of times.” they did win against them, and every time they did fight against them, they did use this Dua and did win.” [Tafsir Qurtubi, al-Jami li Ahkam al-Quran, Volume 002, Page No. 89-90, Under the Verse 2:89] —— The Dalil here is, that Allah did accept their Dua before Rasulullah was send. That means, that Allah did not destroy them or did damn them cause of the Tawassul, he did damn them because they did not accept Rasulullah when he did came.
Imam Qurtubi related the tradition through Ibn ‘Abbas: The Jews of Khaybar were often at war with the Ghatafan (tribe). When they confronted each other (in battle) the Jews were defeated. They attacked again, offering this prayer, “(O Lord,) we beg You through the mediation of the Unlettered Prophet (Peace Be Upon Him) about whom You have promised us that you will send him to us at the end of time. Please help us against them.” Ibn ‘Abbas adds: whenever they faced the enemy, they offered this prayer and defeated the Ghatafan (tribe). But when the Prophet (Peace Be Upon Him) was sent, they denied (him). So Allah the Exalted revealed the verse: “And before that they themselves had (prayed) for victory (through the mediation of the last Prophet Muhammad (Peace Be Upon Him) and the Book revealed to him) over the disbelievers,” that is, through your mediation, O Muhammad.
