Sold his OlamHaba - Redeemed it by Mitzva providing for poor bride.

With tears in his eyes, R' Mottel cried to The Rebbe of Apta, "Rebbe, please help me, I need one thousand rubles to marry off my daughter and I have exactly one ruble to my name!"
"Well, one ruble is also something", said the Rebbe, "Go and purchase the first piece of goods that comes your way. Surely, G-d will bless you."

R' Mottel had faith in the words of the Tzaddik and so, encountering a group of rowdy merchants on his way home, his interest was aroused.

"Looking to buying something?" one merchant called out mockingly.

"Yes," he replied," I have one ruble."

"One ruble! Ha! Well, I have something I can sell for one ruble-my portion in the World to Come!"

And so, a contract was drawn up. Both the buyer and the seller signed their names, and Reb Mottel handed over the coin. The merchants' laughter filled the air.

When the seller's wife inquired what the laughter was about, her husband responded, "You see that beggar over there? I just sold him my portion in the World to Come!"

"What!" she cried. "You sold him the only thing of value that you own!? I want a divorce!"

The merchant was shocked. Didn't she know that this sale was just a joke? But his wife was perfectly serious.

So, the merchant called over Reb Mottel. "I'm afraid our little bargain is off." he told him, "I'll give you back your one ruble, and you give me back my paper."

But, Reb Mottel refused. "I am very happy with my purchase. I have no intention of returning it."

"How about if I add a few rubles compensation for the 'broken contract,'" he chuckled.

"No thanks," replied Mottel. "I won't settle for less than one thousand rubles!"

"What! Are you mad? One thousand rubles??! Forget it! Keep your paper!"

But the merchant's wife insisted. "I promise that if you don't buy that paper back, I will have a divorce this very day! I won't spend my life with a man who sold his portion in the World to Come!

The merchant realized he had no choice. He gave one thousand rubles to Reb Mottel who handed him back the document. Reb Mottel then told the seller's wife the words of the Apter Rebbe. She was so impressed that she went to visit the Rebbe herself.

"Was my husband's portion in the World to Come worth only one ruble?" she asked the Rebbe, painfully.

Responded the Rebbe: "The truth is, before he sold it, it wasn't even worth that much. But when he redeemed it by 'buying' the mitzva of dowering a bride, the value of his Future Life soared, for such a mitzva cannot be measured in money!"
