The heart of a wali is pure love towards Allah (the Exalted) and there is no room for dislike of anyone. Their hearts are directed towards Allah (the Exalted) and not to creation.
Allah loves all his servants but those who He brings close to him are given special favour because of a secret. This is the meaning of the word wali; the one who has been brought close. As for the secret; the Wali draws closer to Allah (the Exalted) through a consistent action of something.
This can be generally said about all miracles.
One of the stories, quoted in the above text, is when a wali kept telling people the means to cure their illnesses. When another wali found it he admonished him and told to desist which he did not heed. Later, he was afflicted with dire stomach pain and affirmed the wali’s opinion. Then he asked him to pray for him but he refused, so the wali died."
Note that every miracle of a wali is a miracle of the Prophet (may Allah bestow peace and blessings upon him). So there is no way to count the miracles of the Prophet (may Allah bestow peace and blessings upon him) because they are increasing day by day.
Also note that those things that will occur at the hands of the Dajjal/The imposter are deceptions/Irkhas.
1. Actual experience,
2. Sound knowledge,
3. High aspiration,
4. Happy condition and 5. Piercing insight.
Five things that make him unworthy to be Sheikh (spiritual leader):
1. Ignorance of the religion,
2. Abandoning the sacredness of the Muslims,
3. Interfering in what does not concern him,
4. Following his passions in everything and 5. Bad character without heed.”
This hadith does not have a sound chain according to Al-Sakhawi in Al-Maqasad Al-Hassanah but it has been proven over time.
There are many Awliyah who did not receive any formal education but when Allah (the Exalted) made them Awliyah he bequeathed them knowledge of the scared law, like Ibrahim Al-Khawas (may Allah be pleased with them).
So if someone's Sheikh has a large following keep your tongue away from backbiting and slandering him. Avoid slandering and backbiting anyone, especially a wali.
As for those who are destroying the graves of the Awliyah this is not just a cowardly act but a foolish one. I would like to see the ending of those who have done such a wretched thing.
Know that the people do not choose the Awliyah, Allah does. So this is why the Awliyah have so many enemies because people hate them.
The picture is the grave of Ottoman ruler Abdulaziz Hamid the second, he was known to have taken the Shadhali path, who had taken the hand of Sheikh Abu Huda Al-Siyadi (may Allah show them both mercy). Some say that he was a Wali because he keep the Ottoman empire from folding and after his time did the caliphate stutter and fall.
