What is the assessment of performing acts of worship in the last ten days of Ramadan, including: completing 20 rak'ahs of Tarawih, reading two parts (Juz') of the Qur'an, and reading the last third of a part (Juz') in the night vigil (Qiyam al-Layl) from 2:30 AM to 4:00 AM? And is this considered a good deed? And how can one compensate for missing the 25th night of Ramadan due to illness?

The last ten days of Ramadan (definition) are a great opportunity to seize good deeds. Whatever acts of worship a Muslim performs during them, he is rewarded for them. The Prophet, peace and blessings be upon him, exerted himself during them more than he did at other times, by enlivening his nights, waking his family, and performing i'tikaf (spiritual retreat). A Muslim is also credited with the reward for the righteous deeds he used to perform if he becomes unable to do them due to illness, based on the Prophet's saying, "If a servant falls ill or travels, he is credited with the like of what he used to do when he was a resident and healthy." Thus, a Muslim's illness does not prevent him from receiving the reward for his previous night prayers, out of Allah's grace. It is recommended to increase good deeds, as they are a Muslim's helpful provision.
