Prayer is something we can ask our Lord for at any time, in any place, in any situation. With the belief that Allah listens to everyone. And the belief, every prayer is accepted.
When a person becomes helpless, when he does not get any help, then only Allah is his last hope. So how can Allah leave such a person empty-handed?
Of course, no one can love man as much as Allah loves him. Allah always looks at His servant when he asks me, and I give him.
Opportunities for prayer:
making Du'a 'during iqamat salat, making Du'a' after the obligatory prayers. Praying at the specific time of Jumu'ah al-Mubarak, praying at the time of the previous night, i.e. at dawn. Praying during rain, praying during jihad, praying in Mataf and near Hujra Sood, praying during Arafat and Rami Jamar.
The Prophet (peace be upon him) has filled the entire life of the Ummah with prayers in view of the blessings and importance of Du'a.
There is a long list of occasions when the Prophet (peace and blessings of Allah be upon him) prayed. We know them from the best(masnoun) prayers.
Today, thank God, there are hundreds of books in the market that combine all these prayers. Therefore, they should be used. Some prayers are so short that they are very easy to remember. These prayers are a source of blessing and mercy and a great spiritual support.
Prayer(supplication) times:
Imagine that the Prophet (peace and blessings of Allah be upon him) conveyed the words of supplication to the corners of life in order for the servant to establish contact with his Creator and Master.
Du'a at the beginning and end of the meal — Dua for entering and leaving the house, Dua for entering and leaving the mosque, Dua for ablution, Du'a for traveling and returning, Dua for meeting, Morning and evening The prayer of day and night, the prayer of sleep, the prayer of waking up.
Du'a for going in and out of the toilet, dua for getting dressed, du'a for business, du'a for riding, du'a for avoiding diseases, calamities, and earthquakes.
Assuming that there are no ups and downs of life for which dua has not been inculcated. There is absolutely no restriction on praying in a one's mother tongue as it strengthens the expression of emotions.
But the words, and phrases of the Qur'anic and Sunnah supplications have an invisible effect and have an eternal effect on human life.
All that is required is belief, and then action. It should also be borne in mind that the effect of supplications given by the Qur'an and the language of Prophet hood is twofold. It is important that some such prayers be preserved in the heart of every Muslim, and that they be made a means of accepting their supplications.
Alhamdulillah(Praise be to God)! This is remembered by every Muslim. The Prophet (peace and blessings of Allah be upon him) called it a comprehensive supplication. Saying only Alhamdulillah is also a supplication. Jazakullah has also been counted in this regard. And above all...., these are all beautiful and memorable prayers. May Allah accept all these prayers in our favor and acquaint us with the manner of asking for prayers, giving prayers and receiving prayers.
The opportunities for making dua you mentioned in your post are often under utilized by most of us, myself inclusive. More often than not the reason most persons turn to dua is when they are in problems or need Allah's aid.
