In Islam, duʿāʾ (Arabic: دُعَاء, plural: ʾadʿiyah أدْعِيَة), literally meaning "invocation", is an act of supplication. The term is derived from an Arabic word meaning to 'call out' or to 'summon', and Muslims regard this as a profound act of worship.
It's greatly noble that they are very good people, and for sure their nurturing contributed to your personality as well.
As you know, religion and becoming religious is a choice that must come from within. Even as Muslims, we always pray to Almighty God to keep us "guided" on the right path. Hidayah, or guidance is in the hands of the Almighty. If your grandparents, or anyone else around you has a potential that Allah ta'ala sees in them, then they will be guided to the light of Iman. If they do not "convert" to Islam, it does not mean they are evil, but just that hidayah is with the Almighty.
The best thing you can do is set yourself with high standards in your conduct, in your ambitions in life, and show those around you how a true Muslim should be.
That itself is a great form of conveying the message of Islam, and then it is up to them to investigate, or ask questions, and so on.
If you see that your grandparents are interested, or have questions, discuss what you know with them. However, never allow it to become an argument, or upset them, as they are your grandparents.
In any case, always do dua for yourself, your parents, your grandparents, your siblings and everyone else, that God showers them with His compassion and Mercy. Ask the Almighty to enlighten your hearts, and ask Him for guidance.
You can also do tawassul to Ahlul Bayt (a.s.), to give you the strength you need, and introduce them to Ahlul Bayt (a.s.), in a positive manner. You dont know what the outcome will be, but at least they will think positive of your religion, and understand you more.
With prayers for your success.
No one seeks or supplicates for evil, knowing that it is from evil, but many human beings seek and supplicate and try to get something which is in fact bad and evils for them but they do not know that at that time. That is why we read in the next sentence in the same verse : Human being is hasty.
Hasty desires are bad and can lead man to evil with out his knowledge. Man needs to think properly before seeking anything and ponder on the possible sequences. A narration from Imam Jafar Al-Sadiq (AS) says: "Distinguish the way which saves you from the way which destroys you, so that you should never seek what can destroy you thinking that is will save you. Allah (SWT) says: Man seeks evil as he seeks good, and the man is hasty." Tafseer Al-Amthal, V. 8, P.418.
Yes, it is allowed.
Allah (SWT) has promised in Quran to respond to the Du'a (supplication) and there is no Du'a with out response. (Your Lord said: Seek from me, I will respond to you) وقال ربكم ادعوني أستجب لكم(Sura 40, verse 60).
We do not know how and when the respond will come. Allah (SWT) knows the best time and best way to respond to any Du'a. Our expectations are according to what we know, but Allah (SWT) knows everything and He is The Most Merciful, The Absolute Wise, so we should leave it to Him. Our mercy on the oppressed can never be more than Allah's mercy on them. He will definitely compensate them in the best way in the best time.
The main things one should consider in looking for a spouse is religiosity and good manners. However there is no problem in preferring a specific type or also marrying someone if you like their culture.
Let's say for example that a woman wanted a Persian looking husband and liked Persian culture; this preference wouldn't be an issue as long as she pursued this in a halal manner.
So you may make dua for a religious spouse who fits your personal preferences.
May Allah grant you success
In the name of Allah
Yes. Reciting any dua and supplication is allowed during the period.
Keep in mind that touching the sacred names of Allah, the Holy Prophet, and the Imams peace be upon them is forbidden in the state of period.
Also if the Dua contains a verse of the Holy Quran, it's okay to recite them, but be careful not to touch those words.
If a person promises Allah (SWT) to do or not to do something, he must fulfill his promise with out fail. If he breaks his promise, he has then committed a sinful act and must expiate by either fasting two months or feeding sixty poor believers. This is called Kaffara of 'Ahd كفارة العهد.
Understanding the meaning of Du'a is better than reading with out understanding.
Sawab depends on the intention and degree of the sincerity and dedication, not merely on the language.
In the technical sense of the use of the word "authentic (sahih)", with respect to having a solid, complete chain of narration and solid textual sourcing, Du'a Sanamay Quraysh is not authentic.
(I say "technical sense" to specify what is meant because there are a lot of ways that people casually use the word "authentic" today.)
As for whether Imam 'Ali (A) actually said it... God knows best.
In any case, you have the option to recite it if it calls to you and you find benefit in it, and you have the option to leave it aside if you prefer to.
Thank you for your question. Reciting whilst not knowing the rules of tajwid is not a sin, but a person should endeavour to pronounce the Arabic properly.
May you always be successful
