This is exactly what was been taught by the Prophet Muhammad to Muslims. Seeking help from the Prophet (SAWA) and his Ahlul Bayt (AS) is because they are the most humble servants of Allah (SWT) and their intercession to Allah (SW) is very helpful to us.
Some ignorant Wahabis claim that seeking help frm non than Allah is Shirk, because they do not understand Quranic verses and Prophetic Hadeeths. In Quran we read that prophets e.g. Prophet Sulaiman did seek help from people. (Sura Al-Naml, Verse 38).
Authentic famous Hadeeth known as the Hadeeth of the blind, narrated by Uthman Bin Hunaif (Tirmithi 3578, and Ibn Khuzaimah 2/225, and Al-Tabaraani 9/17, and Al-Haakim in Al-Mustadak1/707 and mentioned by Al-Albani as authenic (Saheeh)) states that a blind man requested help from the Prophet (SAWA) to get cure from blindness. The Prophet (SAWA) told him to perform Wudhu and pray Salaah and pray in the Sojood of his Salaah: O Allah, I seek from you by your Prophet, The Prophet of Mercy, O Mohammad, I pray to my Lord and your Lord by you, to intercede and get met my need fulfilled.
روى الترمذي بسنده عن عثمان بن حنيف أن رجلا اعمى اتى النبي صلىالله عليه وسلم فقال: اني اصبت في بصري، فادع الله لي، قال: اذهبفتوضأ، وصل ركعتين ثم قل: اللهم اني اسألك واتوجه اليك بنبي محمد،نبي الرحمة، يا محمد اني استشفع بك على ربي، في رد بصري، وفيرواية ( في حاجتي لتقضي لي، اللهم شفعة في ) ( ثم قال صلى الله عليهوسلم ): وان كانت حاجة فافعل مثل ذلك ..
The Prophet (SAWA) do not each but the Truth, and we are the real followers of the Prophet (SAWA).
