May He grant you according to your heart. A story is told about Rabban Gamliel who went to visit Chalafah ben Kroya and asked him to pray for him. Chalafah responded, "May He grant you according to your heart." Rabbi Huna bar Rav Yitzhak said that Chalafah did not actually say those words, but rather he said, "May God fulfill all of your requests." This is a prayer that one should not pray for just anyone, because sometimes a person may have intentions to steal or commit a sin. However, when a person's heart is whole before God, one can pray for them that "God fulfill all of your requests."
