Are you really ready for such signs?
This is from a famous sermon of Imam Ali (a) (near the end of it):
I was with him when a party of the Quraysh came to him and said to him, "O Muhammad, you have made a big claim which none of your fore-fathers or those of your family have made. We ask you one thing; if you give us an answer to it and show it to us, we will believe that you are a prophet and a messenger, but if you cannot do it, we will know that you are a sorcerer and a liar."
وَلَقَدْ كُنْتُ مَعَهُ(صلى الله عليه وآله) لَمَّا أَتاهُ المَلاَ مِنْ قُريْش، فَقَالُوا لَهُ: يَا مُحُمَّدُ، إِنَّكُ قَدِ ادَّعْيْتَ عَظِيماً لَمْ يَدَّعِهِ آبَاؤُكَ وَلاَ أحَدٌ مِن بَيْتِكَ، وَنَحْنُ نَسَأَلُكَ أَمْراً إِنْ أَجَبْتَنَا إِلَيْهِ وَأَرَيْتَنَاهُ، عَلِمْنَا أَنَّكَ نِبِيٌّ وَرَسُولٌ، وَإِنْ لَمْ تَفْعَلْ عَلِمْنَا أَنَّكَ سَاحِرٌ كَذَّابٌ.
The Messenger of Allah said: "What do you ask for?" They said: "Ask this tree to move for us, even with its roots, and stop before you." The Prophet said, "Verily, Allah has power over everything. If Allah does it for you, will you then believe and stand witness to the truth?" They said "Yes". Then he said, "I shall show you whatever you want, but I know that you won't bend towards virtue, and there are among you those who will be thrown into the pit, and those who will form parties (against me)." Then the Holy Prophet said: "O tree, if you do believe in Allah and the Day of Judgement, and know that I am the Prophet of Allah, come up with your roots and stand before me with the permission of Allah." By Him who deputed the Prophet with truth, the tree did remove itself with its root and came with a great humming sound and a flapping like the flapping of the wings of birds, till it stopped before the Messenger of Allah and cast its higher branches over the Prophet, while some of its branches came down onto my shoulders, and I was on the right side of the Holy Prophet.
فَقَالَ لهم (صلى الله عليه وآله): «وَمَا تَسْأَلُونَ؟». قَالُوا: تَدْعُو لَنَا هذِهِ الشَّجَرَةَ حَتَّى تَنْقَلِعَ بِعُرُوقِهَا وَتَقِفَ بَيْنَ يَدَيْكَ. فَقَالَ (صلى الله عليه وآله): «إِنَّ الله عَلَى كُلِّ شَيْء قَدِيرٌ، فإِنْ فَعَلَ اللهُ ذلِكَ لَكُمْ، أَتُؤْمِنُونَ وَتَشْهَدُونَ بِالْحَقِّ؟». قَالُوا: نَعَمْ. قَالَ: «فَإِنِّي سَأُرِيكُمْ مَا تَطْلُبُونَ، وإِنِّي لاَعْلَمُ أَنَّكُمْ لاَ تَفِيئُونَ إِلَى خَيْر، وَإِنَّ فِيكُمْ مَنْ يُطْرَحُ فِي الْقَلِيبِ، وَمَنْ يُحَزِّبُ الاْحْزَابَ».
ثُمَّ قَالَ: «يَا أَيَّتُهَا الشَّجَرَةُ إِنْ كُنْتِ تُؤمِنِينَ بِاللهِ وَاليَوْمِ الاْخِرِ، وَتَعْلَمِينَ أَنِّي رَسُولُ اللهِ، فَانْقَلِعِي بعُرُوقِكِ حَتَّى تَقِفِي بَيْنَ يَدَيَّ بِإِذْنِ اللهِ». فَوَالَّذِي بَعَثَهُ بِالْحَقِّ نَبِيّاً لاَنْقَلَعَتْ بِعُرُوقِهَا، وَجَاءَتْ وَلَهَا دَوِيٌّ شَدِيدٌ، وَقَصْفٌ كَقَصْفِ أَجْنِحَةِ الطَّيْرِ، حَتَّى وَقَفَتْ بَيْنَ يَدَيْ رَسُولِ اللهِ(صلى الله عليه وآله) مُرَفْرِفَةً، وَأَلْقَتْ بِغُصْنِهَا الاْعْلَى عَلَى رَسُولِ اللهِ(صلى الله عليه وآله)، وَبِبَعْضِ أَغْصَانِهَا عَلَى مَنْكِبِي، وَكُنْتُ عَنْ يَمِينِهِ(عليه السلام).
When the people saw this they said by way of pride and vanity. "Now you order half of it to come to you and the other half of it remain (in its place)." The Holy Prophet ordered the tree to do the same. Then half of the tree advanced towards him in an amazing manner and with greater humming. It was about to touch the Prophet of Allah. Then they said, disbelieving and revolting, "Ask this half to get back to its other half and be as it was." The Prophet ordered it and it returned. Then I said, "There is no god but Allah! O Prophet of Allah, I am the first to believe in you and to acknowledge that the tree did what it did just now with the command of Allah, the Sublime, in testimony to your Prophethood and to heighten your word”. Upon this all the people shouted, "Rather a sorcerer, a liar; it is wonderful sorcery, he is very adept in it. Only a man like this (pointing to me) can stand testimony to you in your affairs."
فَلَمَّا نَظَرَ الْقَوْمُ إِلَى ذلِكَ قَالُوا ـ عُلُوّاً وَاسْتِكْبَاراً ـ : فَمُرْهَا فَلْيَأْتِكَ نِصْفُهَا وَيَبْقَى نِصْفُهَا. فَأَمَرَهَا بِذلِكَ، فَأَقْبَلَ إِلَيْهِ نِصْفُهَا كَأَعْجَبِ إِقْبَال وَأَشَدِّهِ دَوِيّاً، فَكَادَتْ تَلْتَفُّ بِرَسُولِ اللهِ (صلى الله عليه وآله). فَقَالُوا ـ كُفْراً وَعُتُوّاً ـ : فَمُرْ هذَا النِّصْفَ فَلْيَرْجِعْ إِلَى نِصْفِهِ كَمَا كَانَ. فَأَمَرَهُ فَرَجَعَ. فَقُلْتُ أَنَا: لاَ إِلهَ إِلاَّ اللهُ، إِنِّي أَوَّلُ مْؤْمِن بِكَ يَا رَسُولَ اللهِ، وَأَوَّلُ مَنْ آمَنَ أَنَّ الشَّجَرَةَ فَعَلَتْ مَا فَعَلَتْ بِأَمْرِ اللهِ تَصْدِيقاً لِنُبُوَّتِكَ، وإِجْلاَلاً لِكَلِمَتِكَ. فَقَالَ الْقَوْمُ كُلُّهُمْ: بَلْ سَاحِرٌ كَذَّابٌ، عَجِيبُ السِّحْرِ خَفِيفٌ فِيهِ، وَهَلْ يُصَدِّقُكَ فِي أَمْرِكَ إِلاَّ مِثْلُ هذَا (يَعْنُونَنِي).
My comment: Quran shows people will always say they will believe such signs, but when tested with it, accuse of sorcery.
My question to you, what reasoning and logic do you have that you are certain such signs are not act of magic and sorcery but truly power from God and proof of the person's station as a trusted agent of God?
I believe if you turn to God often enough for such signs and that you wish to be guided by such signs, you will be. Just don't hasten it, and prepare your heart for it, and ask God sincerely.
