Jami` at-Tirmidhi Book 48, Hadith 177
“The stingy person is the one before whom I am mentioned, and he does not send Salat upon me.”
“May the man before whom I am mentioned - and he does not send Salat upon me - be humiliated. And may a man upon whom Ramadan enters and then passes, before he is forgiven, be humiliated. And may a man whose parents reached old age in his presence, and they were not a cause for his entrance to Paradise, be humiliated.”
“O Allah, cool my heart with snow and hail and cold water. O Allah, cleanse my heart of sins as You cleanse a white garment of filth (Allāhumma barrid qalbī bith-thalji wal-baradi wal-mā’il-bārid. Allāhumma naqqi qalbī min al-khaṭāyā kamā naqqaitath-thawbal-abyaḍa min ad-dannas).”
