You can earn 1000 hasanah each day with one word repeated 100 times in that day! What is this word? SubhanAllah!
This is reported in the hadith Sahih Muslim. Prophet Muhammad (PBUH) asked: “is anyone of you unable to earn 1000 hasanah a day?” The Sahaba wondered how they can possibly earn 1000 hasanah a day. Prophet Muhammad (PBUH) said: “you say SubhanAllah 100 times, then Allah will write for you 1000 hasanah or 1000 sins will be wiped away!”
It takes 2 minutes to gain 1000 hasanah. We can all spare 2 minutes of the day to earn 1000 hasanah.
SubhanAllah means that we are confirming that Allah is perfect in every single attribute! Besides from getting 1000 hasanah it plants us one tree in Jannah!
