Your question: Can worship only means prayers of five times?
Answer: No, worship means performing x5 a day prayers, making Du’a to God only and asking things to have from Him only and plus there are many things that are considered an act of worship. Worship refers to our efforts of devotion towards the Divine, such as daily ritual prayer (salat), fasting in Ramadan (sawm), yearly almsgiving to the poor (zakat), and the pilgrimage to Mecca (hajj). It also includes one’s (optional) daily routine of litanies, such as reading the Qur’an, supplication, etc. as God Says:
”Righteousness is not that you turn your faces toward the east or the west, but [true] righteousness is [in] one who believes in God, the Last Day, the Angels, the Book, and the prophets and gives wealth, in spite of love for it, to relatives, orphans, the needy, the traveller, those who ask [for help], and for freeing slaves; [and who] establishes prayer and gives Zakah; [those who] fulfil their promise when they promise; and [those who] are patient in poverty and hardship and during battle. Those are the ones who have been true, and it is those who are the righteous.” [Quran: 2:177]
In Islam, the performing of one's duties is also considered an act of worship. The Prophet ￼ told us that whatever one spends on his family will be counted as an act of worship for which he will be rewarded, provided what he spent was acquired by Islamically acceptable means. Kindness to family members, no matter how small, is also viewed as an act of worship. Even activities that we enjoy very much, such as sexual relations with one's spouse, are considered acts of worship as long as they are performed in accordance with the relevant Quranic and prophetic guidelines. For example, the Prophet ￼ once told his Companions that they would be rewarded even for engaging in sexual intercourse with their wives. They were astonished and asked: “Are we to be rewarded for doing something that we enjoy very much?"
The Prophet ￼ replied: “If you satisfy your desires illegally, will you be punished?"
They replied: "Yes."
the Prophet ￼ said: "So for satisfying it legally with your wives, you will be rewarded."
