First Shahahdah conveys reality of Tawheed and `Ibaadah Most people do not understand the two Shahahdahs as they should, so they have associated others with Allaah and turned away from Him.
Is it sufficient to pronounce the Shahahdah? Is it sufficient to pronounce the first Pillar of Islaam, that is the Shahahdah (Testimony of Faith)?
Tawheed comes first The Prophet (صَلَّىاللهُعَلَيْهِوَسَلَّمَ) only commanded them to perform Salaah and pay Zakaah after they had declared their belief in Tawheed.
Muhammad last Prophet ordered to believe in before speaking about other Prophets Since Muhammad (صَلَّىاللهُعَلَيْهِوَسَلَّمَ) is the last Messenger, it is obligatory upon people both during his time and after to believe in him first.
