Do you think that you will enter Paradise without suffering trials, without tests, without adversities? Allah (swt) says:

 وَلَنَبْلُوَنَّكُم بِشَيْءٍ مِّنَ الْخَوْفِ وَالْجُوعِ وَنَقْصٍ مِّنَ الْأَمْوَالِ وَالْأَنفُسِ وَالثَّمَرَاتِ ۗ وَبَشِّرِ الصَّابِرِينَ * الَّذِينَ إِذَا أَصَابَتْهُم مُّصِيبَةٌ قَالُوا إِنَّا لِلَّهِ وَإِنَّا إِلَيْهِ رَاجِعُونَ * أُولَٰئِكَ عَلَيْهِمْ صَلَوَاتٌ مِّن رَّبِّهِمْ وَرَحْمَةٌ ۖ وَأُولَٰئِكَ هُمُ الْمُهْتَدُونَ

(And We will surely test you with something of fear and hunger and a loss of wealth and lives and fruits, but give good tidings to the patient, % Who, when disaster strikes them, say, “Indeed we belong to Allah, and indeed to Him we will return.” % Those are the ones upon whom are blessings from their Lord and mercy. And it is those who are the [rightly] guided.)  (Al-Baqara: 155-157)

Keep in mind that entering Paradise is only through passing the ordeals, Allah (swt) says:

 {أَحَسِبَ النَّاسُ أَن يُتْرَكُوا أَن يَقُولُوا آمَنَّا وَهُمْ لَا يُفْتَنُونَ }

(Do the people think that they will be left to say, “We believe”

and they will not be tried.)  (Al-Ankaboot: 2)

( وَزُلْزِلُوا  ) (and were shaken..): The Arabic word of this phrase has two sections (Zal Zal), the word (Zal) means to fall from one’s place. The Arabic word refers to a series of jerks forwards and backward repeatedly, So this phrase expresses the great tribulations and succession of tragedies and fears they suffer.

( حَتَّىٰ يَقُولَ الرَّسُولُ وَالَّذِينَ آمَنُوا مَعَهُ مَتَىٰ نَصْرُ اللَّهِ ۗ أَلَا إِنَّ نَصْرَ اللَّهِ قَرِيبٌ ) (until [even their] messenger and those who believed with him said, “When is the help of Allah?” Unquestionably, the help of Allah is near).): The believers either ask truly about the arrival of the help of Allah (swt) or their feelings go back and forth between “when is the help of Allah? And “unquestionably, the help of Allah is near”. Meaning, do not complain about the delay of Allah’s Help. It is only some trials, afflictions, ordeals and shaken to test man’s faith and its stability in his heart and to examine his acceptance to what Allah wills, only then victory arrive after patience, as narrated in the Hadith:

“And know that victory comes with patience, relief with affliction,
and hardship with ease”.[1]
