Types of Tawassul

Question:
This one is also asking; Mustafa Abu Mustafa is asking about tawassul (seeking nearness to Allah through a means). He says: What are its types?

Answer:
Its types are numerous: seeking nearness to Allah through His names and attributes You say, “O Merciful, have mercy on me; O Forgiver, forgive me,” and so on, calling upon Allah by His names and attributes and seeking nearness to Him through them, as Allah the Exalted said: “So call upon Him by them.” Thus, you call upon Allah by His names and attributes. Likewise, seeking nearness to Allah through the righteous deeds you have performed: you seek nearness to Him through your righteous deeds“Our Lord, indeed we have believed” You seek nearness to Allah through your deeds, as in the hadith of the three men who were trapped when a rock fell on them and blocked the entrance to the cave. They sought nearness to Allah through their righteous deeds, so Allah relieved them, moved the rock away from them, and they walked out.
One of them sought nearness to Allah by his dutifulness to his parents. The second sought nearness to Allah by his fear of Allah, avoiding falling into zina (unlawful sexual intercourse) when he had the opportunity with a woman he desired. When he had the opportunity and nothing remained but to commit the act, she said to him, “O this one, fear Allah and do not open the seal except with its right.” So the fear of Allah took hold of him, and he stood up and left her, leaving the money he had given her, which was a great amount, with her out of fear of Allah.
The third sought nearness to Allah by his trustworthiness and his preservation of the wages of a worker who had left them with him. He increased them for him until they reached a large sum. So when they sought nearness to Allah by these righteous deeds, Allah the Exalted relieved them.
Likewise, tawassul to Allah by the supplication of the righteous: that you ask your Muslim brother to call upon Allah for you. This is from the permissible tawassul. 'Umar ibn al-Khattab (may Allah be pleased with him) sought nearness to Allah by al-Abbas, the uncle of the Messenger (peace and blessings be upon him), during the prayer for rain. He said (may Allah be pleased with him): “O Allah, we used to seek nearness to You by Your Prophet, and You would give us rain when the Prophet (peace and blessings be upon him) was alive, seeking nearness by his supplication. When he died, they sought nearness by his uncle al-Abbas.” Then 'Umar said, “And we seek nearness to You by the uncle of our Prophet, so give us rain.” He said, “Call upon Allah, O al-Abbas.” So he called upon Allah, and Allah gave them rain. Tawassul by the supplication of the righteous is prescribed. Yes.
