Abu Zur’ah al-‘Iraqi said: I don’t know of any Hadith, that is more authentic than this Hadith, which has so much reward for such a small amount of action.
Do you know which hadith is he referring to?
It’s the authentic Hadith of Aws b. Aws reported by Ahmad and Abu Dawud, that the Messenger of Allah, SallAllahu `alayhi wa sallam, said:
مَنْ اغْتَسَلَ يَوْمَ الْجُمُعَةِ وَغَسَّلَ ، وَبَكَّرَ وَابْتَكَرَ ، وَدَنَا وَاسْتَمَعَ وَأَنْصَتَ ، كَانَ لَهُ بِكُلِّ خُطْوَةٍ يَخْطُوهَا أَجْرُ سَنَةٍ صِيَامُهَا وَقِيَامُهَا
“Whoever does ghusl on Friday and washes his head, and sets out early, and comes close to the imam and listens and keeps quiet, for every step he takes he will have the reward of fasting and praying qiyaam for one year.”
Another amazing Hadith is that of Salman al-Farisi who narrated that the Messenger of Allah, SallAllahu `alayhi wa sallam, said:
لَا يَغْتَسِلُ رَجُلٌ يَوْمَ الْجُمُعَةِ وَيَتَطَهَّرُ مَا اسْتَطَاعَ مِنْ طُهْرٍ وَيَدَّهِنُ مِنْ دُهْنِهِ أَوْ يَمَسُّ مِنْ طِيبِ بَيْتِهِ ثُمَّ يَخْرُجُ فَلَا يُفَرِّقُ بَيْنَ اثْنَيْنِ ثُمَّ يُصَلِّي مَا كُتِبَ لَهُ ثُمَّ يُنْصِتُ إِذَا تَكَلَّمَ الْإِمَامُ إِلَّا غُفِرَ لَهُ مَا بَيْنَهُ وَبَيْنَ الْجُمُعَةِ الْأُخْرَى
“If a man takes a bath on Friday, and purifies himself as much as possible, oils his hair, applies whatever perfume available in his house, sets forth (for the mosque), does not separate two people (to make a seat for himself), performs Salat what is prescribed for him, remains silent when the Imam speaks, his sins between that Friday and the following Friday will be forgiven.”
Don’t forget to add some sadaqah to your good deeds on this day. Ka’b b. Malik said as reported by Ibn Abi Shaybah:
“(Reward of) Al-Sadaqah (charity) is multiplied on the day of Jumu’ah.”
