Ibn al-Qayyim رحمه الله:

“The greenery and verdure of this world is like a tree. The rapid manner in which the world vanishes away bit by bit is like the shade. And the slave is a traveler heading toward the meeting with his Lord. When the traveler sees a tree on a hot day, he does not deem it appropriate to build a home under the tree or take it as a permanent residence; rather he shades himself according to his need. If he exceeds this, he is cut off from his companions.”

[The Dunya & Its Reality | Pg. 18]

Ibn Al-Qayyim (رحمه الله) said:

“Whoever is truthful and sincere in his reliance upon Allah to achieve or obtain something, he will (certainly) obtain it (and better than it, and it will be made easy for him).”

[Madaarij as-Salikeen, 2/114]

Be patient:

By Allãh, there's only a small amount of time left before the aid of Allãh comes. The Messenger of Allãh (ﷺ) informed us that:

بَدَأَ الإِسْلاَمُ غَرِيبًا وَسَيَعُودُ غَرِيبًا فَطُوبَى لِلْغُرَبَاءِ

Islãm started as something strange, and it will return to being something strange, so give the glad tidings of Tûbâ (a tree in Jannah) to the strangers.

[Sahih Muslim 145]

Ibn al-Qayyim رحمه الله:

“Since their creation, people have always been travelers,
‏
And they have no place to go,

Except in heaven or hell.”

‏[الفوائد (٢٧٦)]

Ibn al-Qayyim رحمه الله:

“Nothing can be beneficial to the heart like reciting the Qur’ān meditatively. It causes one to have love for Allāh, passion, fear, beseeching Allāh, reliance upon Him, gratefulness to Allāh and patience, in addition to everything that puts life into the heart.”

[Miftāh Dār as-S’ādah | Pg. 187]

Ibn al-Qayyim رحمه الله:

“Supplication is remembrance of the One being called upon, Exalted is He; it includes requesting from Him and praising Him by His names and attributes; thus, it is remembrance and more.”

Ibn Qudāmah said: "And know that many men were destroyed due to their fear of people's criticism and love for their praise."

‎● {مختصر منهاج القاصدين}

‌‏قال سفيان بن عيينة رحمه الله : ليس العاقل الذي يعرف الخير والشر
إنما العاقل الذي إذا رأى الخير اتبعه
وإذا رأى الشر اجتنبه

Sufyān b. ‘Uyaynah Raḥimahullāh: “Intelligent is not the one who is aware of good and bad rather intelligent is the one who when sees good, follows it and when sees evil, avoids it.”

‎● [شعب الإيمان للبيقهي]

Prophet Muḥammad ﷺ said: “And indeed, it may be that Allāh aids this religion through a sinful man.”

● [رواه البخاري ٢٨٩٧]

Ibn al-Qayyim رحمه الله said:

‎“If the heart is troubled and worried it has nothing to be comforted with,

‎except the remembrance of Allāh.”
