Because there was more hope of getting the Night of Judgment in the Ushra and Akhira, the two scholars, peace and blessings of Allah be upon them, used to organize more worship in the Ushra and Akhira.
کان رسول اللہ صلی اللہ علیہ و سلم یجتھد فی العشر الاواخر مالا یجتھد فی غیرہ.
(Muslim Sharif)
The more the Prophet (peace and blessings of Allah be upon him) used to work hard in worship during the last ten days of the last ten days, the more he did not do anything else. Be organized because some of them may be valuable overnight. You said
تحروا لیلۃ القدر فی الوتر من العشر الاواخر من رمضان
(Bukhari Sharif)
Search for the Night of Qadr in the odd nights of the last ten days, that is, worship in those nights.
It is said in the hadith that when the night of Qadr comes, Hazrat Jibreel (peace be upon him) descends with a group of angels and showers mercy from Allah on those who are standing or sitting and remembering Allah (Bayhaqi).
However, those who wish that the worship of one night will get the reward of more than eighty-three years of worship, their previous sins will be forgiven and the blessings of Allah will descend on them, then they should do as much as they can in every night of Ramadan. If possible, do worship in the form of prayer, recitation and remembrance, if not, at least in the last ten days, i.e. from the twentieth of Ramadan, organize maximum worship every night. May Allah Ta'ala bless us and you with this, Ameen
