✅ Answer: First, the relevant narration is mentioned:

مُحَمَّدُ بْنُ یَعْقُوبَ عَنْ مُحَمَّدِ بْنِ جَعْفَرٍ عَمَّنْ ذَکَرَهُ عَنِ الْخَشَّابِ عَنْ عَلِیِّ بْنِ حَسَّانَ عَنْ عَبْدِ الرَّحْمَنِ بْنِ کَثِیرٍ عَنْ دَاوُدَ الرَّقِّیِّ قَالَ کُنْتُ عِنْدَ أَبِی عَبْدِ اللَّهِ إِذِ اسْتَسْقَی الْمَاءَ فَلَمَّا شَرِبَهُ رَأَیْتُهُ قَدِ اسْتَعْبَرَ وَ اغْرَوْرَقَتْ عَیْنَاهُ بِدُمُوعِهِ ثُمَّ قَالَ لِی یَا دَاوُدُ لَعَنَ اللَّهُ قَاتِلَ الْحُسَیْنِ [فَمَا أَنْغَصَ ذِکْرَ الْحُسَیْنِ لِلْعَیْشِ إِنِّی مَا شَرِبْتُ مَاءً بَارِداً إِلَّا ذَکَرْتُ الْحُسَیْنَ ] وَ مَا مِنْ عَبْدٍ شَرِبَ الْمَاءَ فَذَکَرَ الْحُسَیْنَ ع وَ أَهْلَ بَیْتِهِ وَ لَعَنَ قَاتِلَهُ إِلَّا کَتَبَ اللَّهُ عَزَّ وَ جَلَّ لَهُ مِائَةَ أَلْفِ حَسَنَةٍ وَ حَطَّ عَنْهُ مِائَةَ أَلْفِ سَیِّئَةٍ وَ رَفَعَ لَهُ مِائَةَ أَلْفِ دَرَجَةٍ وَ کَأَنَّمَا أَعْتَقَ مِائَةَ أَلْفِ نَسَمَةٍ وَ حَشَرَهُ اللَّهُ یَوْمَ الْقِیَامَةِ (ثَلِجَ الْفُؤَادِ)

Translation: Dawood Raqi said: I was with Imam Sadiq (peace be upon him) when he requested water. When he drank it, I saw his eyes fill with tears, and he began to weep. Then he said to me: 'O Dawood, may Allah curse the killer of Hussein. How bitter is the memory of Hussein! Indeed, I never drink cold water without remembering Hussein.' He continued, 'There is no servant who drinks water, remembers Hussein and his family, and curses his killer except that Allah, the Almighty, grants him one hundred thousand good deeds, erases one hundred thousand sins, raises him one hundred thousand degrees, and it is as if he has freed one hundred thousand slaves in the way of Allah. Moreover, Allah will resurrect him on the Day of Judgment with a heart full of tranquility.'

✅ As seen in this narration, it specifically refers to drinking water and may not necessarily apply to other beverages. However, we present a general hadith that can be followed whenever we remember our oppressed master:

مُحَمَّدُ بْنُ یَعْقُوبَ عَنْ عِدَّةٍ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ الْقَاسِمِ بْنِ یَحْیَی عَنْ جَدِّهِ الْحَسَنِ بْنِ رَاشِدٍ عَنِ الْحُسَیْنِ بْنِ ثُوَیْرٍ قَالَ کُنْتُ أَنَا وَ یُونُسُ بْنُ ظَبْیَانَ عِنْدَ أَبِی عَبْدِ اللَّهِ وَ کَانَ أَکْبَرَنَا سِنّاً فَقَالَ لَهُ إِنِّی کَثِیراً مَا أَذْکُرُ الْحُسَیْنَ فَأَیَّ شَیْ ءٍ أَقُولُ قَالَ قُلْ صَلَّی اللَّهُ عَلَیْکَ یَا أَبَا عَبْدِ اللَّهِ تُعِیدُ ذَلِکَ ثَلَاثاً فَإِنَّ السَّلَامَ یَصِلُ إِلَیْهِ مِنْ قَرِیبٍ وَ مِنْ بَعِیدٍ

📚 Al-Kafi, Vol. 4, p. 575

Translation: Hussein ibn Thawir said: Younus ibn Zabyan and I were with Imam Sadiq (peace be upon him), and Younus was the eldest among us. He said: 'I frequently remember Hussein. What should I say at such times?' The Imam replied: 'Say three times: (peace be upon him), for the greeting reaches him whether from near or far.'

صَلَّی اللَّهُ عَلَیْکَ یَا أَبَا عَبْدِاللَّهِ
