Musar for Ketubot 207:6
בשעת פטירתו של רבי זקף עשר אצבעותיו כלפי מעלה אמר רבש"ע גלוי וידוע לפניך שיגעתי בעשר אצבעותי בתורה ולא נהניתי אפילו באצבע קטנה יהי רצון מלפניך שיהא שלום במנוחתי יצתה ב"ק ואמרה (ישעיהו נז, ב) יבא שלום ינוחו על משכבותם
When he was about to die, Rabbi raised his ten fingers towards heaven and said: “Master of the Universe, it is revealed and known to you that I have labored in the study of the Torah with my ten fingers and that I did not enjoy [any worldly] benefits even with my little finger. May it be Your will that there be peace in my resting place.” A heavenly voice went out, and said, “He shall enter into peace; they shall rest on their beds.
Mesilat Yesharim
They further said regarding the holy Rabeinu HaKadosh, who before his death lifted his ten fingers and said: "it is revealed and known to You that I did not derive pleasure from this world, not even to my little finger."
