Here is the correct understanding of WASEELA.
5:35 O You who have chosen to be graced with belief! Be mindful of God and seek earnestly to come closer to Him by obeying His commands, and strive hard in His cause so that you may truly prosper.
[Waseelah = Seeking earnestly = Applying the mind and heart to reach a noble goal. Verses 2:186 and 17:57 are many of the verses that negate the erroneous concept of "Waseelah" denoting some saints, sages or even Prophets interceding on behalf of people]
