We need to remind ourselves about these facts:
1. The Mercy of Allah is much greater that our imaginations and bigger than all the difficulties. Allah says in Quran : And My Mercy involved everything (Sura 7, Verse 156).
2. Allah is The Absolute Able to Grant whatever He wants to whomever He wants. We need to keep on seeking from Him and we should never lose hope in His Mercy.
3. We don't know when it will be good for us to get our wishes, so, we must trust Allah's Wisdom and Mercy which will definitely come whenever Allah Knows that it is good for us.
Wassalam.
