Hadith # 1761
Abu Hurairah (May Allah be pleased with him) said: I heard the Messenger of Allah (PBUH) as saying: "None of you should observe fast on Friday except that he should observe fast either one day before it or one day after it."
[Al-Bukhari and Muslim]
Commentary
We learn from this Hadith that we can fast on Friday if we fast, along with it, on Thursday or Saturday, i.e., either one day before or after it.
