Mulla Salih Mazandarani who is a renowned Shiite scholar had an adventurous life, which is briefly described here. His father, Mulla Ahmad, was so poor that he could not provide for his son's living expenses.
Muhammad, who was then a young adult, went to Isfahan to study in one of the schools there. The school had an endowed property. The income was used to pay some money to each student based on his rank. Muhammad who had just started studying received very little which was insufficient for his daily needs. He suffered so much that he had to study at night under the light of one of the school's lamps.
However, he was so studious that he overcame all deprivations and difficulties and attained a high scholarly status. He managed to attend Mulla Muhammad Taqi Allameh Majlesi's class. A short time later he surpassed all other students and received his wise professor's special attention.
The author of Mirat al-Ahwal wrote: Mulla Salih who was then a young scholar was considering choosing a spouse to marry. Allameh Majlesi became informed of that and one day after his class asked Salih if he would permit him to find him a spouse. He lowered his head and after a moment said yes. Allameh Majlesi got up and went home. He called his learned daughter Amineh Beigom, who had mastered all the sciences perfectly. He said to her: My dear daughter. I have found you a spouse who is extremely poor, but absolutely wise, pious and mature. But it is up to you to decide. The holy noble learned daughter shyly said: "Dear father, being poor is not a defect for men." Thus she expressed her approval of this marriage. At a felicitous hour they held the marriage ceremony and prepared the bride for the groom.
On the wedding night, the groom unveiled her face and found her very beautiful. He went to a corner and started praising God and studying. He ran into a difficult academic issue which he was unable to resolve. Amineh Beigom realized the problem. When he left home the next day, she wrote the answer in full detail and put it in its place. When the man came home that night and saw that his unresolved issue was solved by that knowledgeable woman, he thanked God by placing his forehead on the ground, and prayed all night long.
Thus three days passed. When Allameh Majlesi was informed, he told him: "If this wife is not suitable for you, let me know. I will get you another one."
Mullah Salih replied: "No, that is not the issue. I keep away from her because no matter how much I praise God for this blessing that He has bestowed on me, I cannot be grateful enough."
When Allameh Majlesi heard his answer, he said: "Confessing that one cannot be grateful enough to God is itself the utmost form of being grateful to Him."
